So I'm not going to say what I did, but recently I took off my intake manifold, valve cover, throttle body, coolant tank, fuel rail, and fpr. Replaced all the gaskets, flushed coolant, changed oil, deleted my pcv system am now just venting it into the atmosphere straight off the crankcase.
I did a lot of work and everything went smoothly, pretty positive I have all the hoses/clamps/sensors all tight and attached. But I'm having a couple problems.
Car in question is an AEB 1.8T.
First one is I have a bad idle when the revs come down. When I start the car it'll turn over fine then almost stall out, bounce up and down between 400 rpm and 1000 rpm. Then it'll idle fine after about 4 bounces. Also if I'm just accelerating and get off the throttle and am in neutral, when the revs come down it'll do the same thing.
Next thing I noticed is my car has some smells of gas fumes when I get in it. Not really sure how this happened but really need some input to what this could be.
Lastly, my car feels like it's in limp mode all the time and won't get out of it. It is chipped but for some reason, it'll boost to 4psi and just sit there at WOT. Any clues to what this could be.
I also detached the battery cables to do some things so my ECU was reset which I thought may be the problem since the ECU hasn't adjusted yet to the new timing (idle problem?)
So...what I think it is, is my FPR. I don't know how this could be but it kinda makes sense for these problems. Not sure about the gas fumes but if the fpr isn't regulating the right amount of fuel when the revs change, that's why it'd idling bad. And when boosting it's not putting in enough fuel when it needs to be. But other than these problems, the car runs totally fine once moving and accelerating/cruising. Just when the revs come down and accelerating fast it's weird.
I'm gonna test out my buddies 4bar tomorrow and see if that changes it but I'm really clueless to what the problem is. Any help here would be greatly appreciated or any experiences with the same problems.
Thanks. :thumbup:
