Check the ECT sensor.
Hey guys I've got a 1994 gti 2.0 (obviously) and in the morning when I'm leaving for school the car will not start unless I floor the gas. when its warmed up and i park for a little to start it I still have to give it quite a bit of gas but it is the worst in the morning and I'm getting tired of having to be on the gas hard just to start my car I could really use some advice on what to look into or what should be replaced ! Please and thanks cheers,
so I replaced the ect and I cleaned my MAF sensor also did a tune up while I was at it (new plugs and oil change) after all this I am still having the same issue where I'm having to give the car gas every time I start it , does anyone have anymore info?
I got the ect for $6 because I have a discount at a auto parts store so I figured why not! And yeah it turns over fine and then it revs up to what its suppose to but then if you don't give it gas it just dies I was thinking it might be my idle control but I'm not sure
Ok so it took me a long while to actually find someone locally that carried the IACV but when i did find a store they quoted me the part was $300 anyways instead of spending that kinda money i decided to clean the valve and see if that worked i am still having the same problem though so i took a video in hoping it would give you guys a second look at to what else it could be or if its for sure the idle valve, thanks in advance !
Just cleaning the iac doesn't always fix it, grab one out of the junkyard or ebay to try it. Also before swapping feel/listen if it "clicks" when you turn on the ignition. I can hear mine click from the drivers seat. But others aren't so loud so might need a helper.
I have a similar issue. But mines will actually run for like 10 seconds then die. I believe my issue is MAF related though.
I wonder if your hall sender is going bad? I've read that if it is your car will NOT start or have difficulties starting.
I do use regular fuel! And I checked the cam shaft position sensor it is still good, cleaned my grounds as well still having the same problem! But I am pretty sure now it is the IAC especially because after the car starts it does idle like an absolute pig the car actually shakes I can post of Video up if you guys would like to see! I'm going to try the click thing though thanks for all your suggestions guys much appreciated !
