Hello All, I have a 1988 Jetta GLI, 16V, with an 1989 GLI engine. I just changed my catalytic converter about 2 weeks ago. I changed the oil about 3 weeks ago. I went to get the smog done, and found my NO #'s are double whats allowed in the state of California. All the othe numbers look beautiful. I asked a mechanic friend what he thought I could do to get the NO #'s down, and suggested I may have some carbon on the heads of the pistons. He suggested I get a chemical cleaner (forgot the name of it), and pour it down the spark plugs holes in the head. Let it sit for a few hours and then re-fire up the engine. He suggests this will help the carbon build-up. Any idea if he knows what he is talking about? That sounds abit extreme to me, but what else can I check, to help lower the NO #'s?
Thanks, Brian MICHAEL INGRAM <[email protected]> wrote: Hello all, I never did find any vacuum leaks even though it sure seemed there should have been. As I had said a few days ago while I was working on the car I realized the oxygen sensor wires has came loose and fallen against the exhaust and melted thru so replaced the plugs. I knew the car had been running 1.5 years ago when I took it off the road. Anyway unplugged the oxygen sensor and all hesitation and bog entirely disappeared. Now it does idle up and down(maybe even more than before)but runs pretty good otherwise. I still have not ruled out fuel delivery problems and I am planning to replace (the under car) fuel reservoir assembly due to it being extremely rusted and if there isnt leaks yet there may very well be soon. My questions: The oxygen sensor on our car is this a dealer only item? I remember in the past the mention of an interchangeable sensor from a domestic car..does anyone remember anything about this? I shudder at the thought of buying this from the VW dealer. another question.....I noticed my air stabilizer is running(vibrating) but it clicks often, sya every few seconds??Is this normal? Or is the result of my disconnected O2 sensor? Last question....the complete fuel reservoir are they interchangable say from a 90 jetta (my gti is 89).

Wednesday I got the car off the jackstand after doing a few remaining odd things. Took for a ride and clutch seems fine. New problem car was idling up and down ( I had already cleaned throttle body etc.) so I replaced the air idle stabilizer with one I had lying around. Seems to idle okay once it warms up about 3 or 4 minutes. This is the deal....when it first starts (even though it will stall if I let it) when I give it gas it revs up normal...after just 5 or 6 minutes when I give it gas it bogs down. Now as I said after 5 or 6 minutes it will stay running but when I give it gas it starts to rev a little then bogs down almost immediately.So at first wont stay running but will rev fine. After 5 or so minutes it will idle but bogs down terrible. If I work with it a bit and give it continued pumping it catches and as it works above say 2000 rpm and will rev great then (until I let itgo down into lower rpms...then same thing all over. One more thing..I have to sometimes floor it to get it to start unless its cold (then it starts right up). I cant find any vacuum leaks. Changed the fuel filter while I was under there. Wires are almost new. I believe timing is pretty close.Car did sit for about 1 year and 3 months. I would appreciate any ideas anyone might have.
