I recently put a post in here about my car running like crap... It is an 89 n/a... I just recently replaced everything fuel related under the hood with aftermarket stuff except for the injectors... I know, I know... Why would you do that with an n/a... Its like a 1985 grand am with 20" gold plated wheels... whatever... I have my reasons...

Now it ran great for a week... I took and got it inspected... The guy there said it was running really clean... Out of concern I came here and tried to ask if that was a bad thing... I was met with questions about why I would put that kind of stuff under the hood of an n/a, instead of the question being answered...

I got into it the other night and took it for a highspeed multiple redline ride around the city... It was running beautifully... I hit 100 in what felt like less than 10 seconds (although I doubt the accuracy of my internal clock)...

I parked it in the drive way... Two or three hours later I went out to tuck her in the garage and she started running very rough... I could barely get it into the garage it was so bad... It was smoking bad... Since I am legally color blind, I got my wife to look and she said the smoke was gray... My accross the street neighbor who is manager of parts at some dealership said it was white with a very small tint of blue... He said that he did not smell coolant being burned so he doubts that is the issue... My oil is maintaining its level well so I doubt it is that... I recently filled up on gas and a half tank of that is gone so I doubt it is bad gas... I pulled the entire intake manifold off of the car and resealed it... I tested everything that the fsm told me to... All that was left is the compression test...

I get 3 even bounces to approx 90 - 100 psi... I have searched and read and that is about where the turbos are supposed to be... Would this mean that a rebuild is in order for an N/A?

If the engine is okay and you have any other suggestions please help... I appologize for the long winded thread... Please... No comments on aftermarket fuel systems in N/A's... I gave a list of reasons for my doing so... It would be listed in the for sale section under my name... I was searching for fuel rails...

Edit: Spark plugs where wet and black... Not real oily though
