Did you disassemble the distributor and rotor and clean them too? I usually take mine off when I do the timing belt and wash them really good with dish washing soap and rinse with hot water. That seems to be helpful too. I may do that next.by Bob in Lake Havasu - Technical Forum
A battery can fail internally even when new. It is an easy check to make at the battery terminals. Almost any load will cause it to open up and the voltage will drop. Just turn on the lights and check battery voltage. The battery voltage should be above 12 with no load. With a load it should not drop below 10 even with the starter running. The fuseable link is in the wire and should lookby Bob in Lake Havasu - Technical Forum
That is an interesting thought. The main problem is that when I am trying to start the car, it is because I need to go somewhere and would not likely have an extra 10 minutes to mess with it. Or it is in a parking lot at work or at the store, and this being the Pacific Northwest, raining. My plan is to check the oxygen sensor readings and the distributor cap and rotor.

It could also be an internal failure in the battery. Check the battery load capacity.by Bob in Lake Havasu - Technical Forum
I once thought the same about my problem too but the stumbling when cold seems more like a fuel control problem with mine. I have made no progress but the winter weather has inhibited my enthusiam for being out of doors workking on it.

Yes, I have checked that too. This has been getting worse for quite a few months. The last three days when cold starting, it fires up more quickly than normal. Like it had fuel available in the manifold already. The warm starts were not so bad but then this evening after setting for two hours, it had to be cranked for several seconds to catch. Still a mystery. I might try another set of iby Bob in Lake Havasu - Technical Forum
Thanks for the thoughts Rick, I have had that electrical connector apart, I took it apart to get the injector harness out of the way. The pins and scockets seemed to be clean. Vacuum leaks from hoses in that area might be a good possibility. Have not changed any of those hoses. I will give them a good going over with the engine running to see if there is a bad one. One test (if you can caby Bob in Lake Havasu - Technical Forum
You know, I have considered that but have not figured out how to tell. My thought is that they would not be identically bad. The new ones had been to the Witchhunter cleanning shop and came back with a print out of performance that said they were within specs. Not that it could not happen.by Bob in Lake Havasu - Technical Forum
I will have to look again in the Bentley. Thought I had understood it. In the past, a new or freshened set of injectors completely cured the problem. This time it made almost no difference.by Bob in Lake Havasu - Technical Forum
You bring up some good points Peter. The WOT is what I am not sure of. Would that tell the computer to turn on the injectors if the engine was not seen as running? I put a pressure gage on the fuel return line while I was at the regulator test effort. When the fuel pump is running, there is 15 psi at the regulator on the return line. This means that fuel is flowing back to the tank. Asby Bob in Lake Havasu - Technical Forum
Thanks for all the feed back guys. When the engine is dead cold it starts right up and the idle is high for a second or so then settles to normal. I had the idle control valve off and it worked freely but I put some ether in it to flush out anything that might be there. So not much unusual there. No change afterward. On warm starts if it does start, it seems quite normal. If it does not,by Bob in Lake Havasu - Technical Forum
That is an interesting possibility. Although the fuel consumption does appear to change with engine temp. When cold it takes more fuel on a particular road I drive than when it is warm I am pretty sure. I could check the wire harness. I better check those wiring diagrams for the pin numbers. That brings to mind another possibility too. I have an after market chip in the ECU. Maybe it loby Bob in Lake Havasu - Technical Forum
Try using a hand mirror to inspect the underside of the car when it stinks. Use a flashlight as you can point it at the mirror and make it illuminate what you want to see on the bottom of the car. Might see a stain where fuel is leaking but not enough to form a drip on the floor. I thought the gas lines were on the drivers side, but inspect both sides. Fuel vapor is heavier than air so it wilby Bob in Lake Havasu - Technical Forum
QuoteFlyboy Just a thought, what are your compression numbers like? Mine are on the low side, and I am wondering if it has not got something to do with it. 1. 975Kpa 2. 950Kpa 3. 925Kpa 4. 925Kpa The compression checks last were pretty consistent but have not done one in a while. Generally around 170 psi. The head has probably never been off the block. The valves were adjusted a few monby Bob in Lake Havasu - Technical Forum
1) Did this start all of a suden or did these conditions gradually happen over time It has been getting gradually worse for about a year. Injector cleaner helped at first but now seems to make no difference. 2) Mileage? The car has 224,000 miles now. I replaced the idle control at about 120,000 thinking it was not working but it was. Changed the injectors then and it ran well for quite aby Bob in Lake Havasu - Technical Forum
I have considered doing what you suggest but was not sure what value the computer would use. The stumbling when cold is also annoying as there is a stop sign 40 yards from my drive way and I usually have a time getting it going without dying there. I could just disconnect it for a day and see what it would do. The resistance when hot (180F) 240 ohms, and cooler (129F) 500 ohms, are correct.by Bob in Lake Havasu - Technical Forum
In the past, a clean set of injectors cured this problem for a long time. Even adding some injector cleaner to the fuel helped a lot. This time however the fuel injector cleaner did not make much difference and changing the injectors that had been to the shop for cleaning and testing did not change the problem. That is why I am looking at all the other potential problems. I checked the leak dby Bob in Lake Havasu - Technical Forum

If the parking brake is involved, it should change the sound if the parking brake is gently applied while the noise is there and it should change noticeably. My first thought with the variation in left turn to right turn is that there is a wheel bearing that is worn and become noisy. On each wheel hub there will be two bearings, an inner bearing and an outer bearing. Usually they are capable oby Bob in Lake Havasu - Technical Forum
I changed the injectors to a set that had been through the cleaning shop. Checked the temp sensor when the enging was warm and again when hot. The resistance appears normal. Today I checked the fuel pressure regulator pressure. It is 45 psi. The spark plugs are recently changed.

My 1990 cabrio has been a bit tempermental of late with faltering when cold and occasional hard starting when warm. I had put injector cleaner in to try and help but with less and less success the past few months.

It took about 3 weeks to calm down enough that I could sleep. I was a little disgusted with the doctors as they made me wait till there was a huge rash that was very painful before giving me the medication that would help. I suspected it was Shingles when I went in and said so but they wanted to wait and see. Well it turns out that the sooner the medicine is started, the less severe it gets.by Bob in Lake Havasu - Community Forum
A possibility is the gas cap is not letting pressure out if the temp in the garage is warmer than outside. Could be the relief valve is holding pressure and forcing a leak at the filler pipe. Also might want to check under the inspection cover that is over the fuel pump. There are two hoses there that might need a hose clamp tightened. Fuel filter might also need clamps tightened.by Bob in Lake Havasu - Technical Forum

Just had some work done on my cabrio front fender. I disassembled the bumper and trim myself to keep the cost down. They did not remove the fender for the painting.
