That is when all the trouble started. This thing is super clean. Hope I didn't drop a spring. I am not having any luck with cleaning. In fact, all the cleaning is adding up to BIG dollars. I have worked with small parts for a number of years and find it difficult to believe that it is me who is messing this stuff up. Thanks for your thoughts though.mattb said:Your IAC may be dirty too. Clean it out.
Reading again....maybe I should just give this a shot after all. Sorry I will try this out. Thank you.thefultonhow said:
Heh, could this be the end to our sorrows then? Are you going to try it out? (removing the TPS before restarting) I pm'd the creator of that thread that the fulton mentioned and asked him if it helped. I can't try it today until I get out of work. Other than that its just buy another IACV.pauley01 said:I am right with you on this one. My screw is turned ALL the way in and I cant get my base idle lower then 870 in timing mode. My timing is set at 16. I do not understand. Its not always been like that.
So you do have an extra MAF to diagnose with don't you? If so, did you get the same results with the other part? I know that sometimes a problem in one area may make you think that a totally unrelated part is at fault. My gas mileage seems to be shitty to, but I haven't checked in a while. I am going to give this a shot to. I have cleaned the MAF sensor many times over as well. Have you played with the ARV yet or the coolant temp sensor? I have my old coolant temp sensor for you if you want it to try out and keep. I also have my old ARV. I could ship it down for you to try out. I just don't have another MAFpauley01 said:I am going to try it. My major problem is gas consumption. I have 1/4 tank of gas left and have only been 150 miles. I think my MAF is my main problem. While my car is idling like shit, I can pull the MAF plug and wham...problem is gone. It idles perfect. When I put the plug back on, it starts surging again. I have sprayed MAF cleaner on it multiple times and its not helping.
I hope I have diagnosed this right. Shitty gas mileage, running rich (black muffler tip) and terrible idle. I can rev up to 5K with no problems, so that does make me wonder about the MAF.
That's interesting. I'll try that to. I truly believe that my car was in timing mode while this is happening though. Timing Mark is stable as can be.cavern said:Turn your screw all the way in, then set the car into timing mode. If you did it correctly and the screw is in, it'll die real quick (if everything is clean, and it sounds like you cleaned everything really well).
I see alot of people having hard time getting the car into timing mode correctly...
hmmm, I'll try this method, and report back...I doubt that turning the screw all the way in will result in anything lower than the rpm it is stuck at now though, but it is worth a shot.cavern said:You cant tell by the marks if your in timing mode or not, because you can stick a timing light on (say a digital one) and it will check timing based on what rpm you are at, its just not an accurate reading, thus the marks will show up.
Just keep the car running when you do it, heres what I do.
1. Adjust screw to about half way (motor is off)
2. Turn on car.
3. Warm up car
4. Rev over 3k 3-4 times, letting it drop down to idle each time then back over 3k.
5. Unplug TPS, adjust rpm.
During this step (5) you can turn your rpm really low (screw in) to see if you can get the car to bog, means you are in timing mode correctly.
6. Check Timing.
7. Adjust Distributor
8. Plug TPS back In
