    Trying to get 2.8 running again!

    My Grand Prix quit on me on Thursday. As many of you know, it was running on 5 cylinders. I am trying to get it running again. I know how to check for compression, but I would like to know what all I need to check to see if I'm getting spark to the bad cylinder. A guy on another forum told me...

    2.8L exhaust leak, causing sluggish accleration?

    Well, I decided against the Corsica 3100. I would like to continue running the existing 2.8L. I have noticed very sluggish acceleration. Besides only running on 5 cylinders, the car also has a severe exhaust leak located right after manifold. Is the sluggish acceleration caused by the lack of...

    Put a '94 3100 into '88 Grand Prix?

    I am in the process of getting a 1994 3100 out of a Chevy Corsica to put in my '88 coupe. I've talked to some other guys on another forum and they are saying that I would have to do some modifications to make the 3100 fit. Is this true? I thought that the motor mounts were the same for all...

    Any probs. with '94 3.1?

    I am in the process of getting a '94 3.1 for my '88 Grand Prix. I was just wondering if there were any problems with the 3.1 motors that I need to know about before I swap it in?

    2.8L head

    My '88 2.8 coupe is running on 5 cylinders, I have been told I need one of the heads replaced. Would the head off of a 3.1 work? I don't know if this matters, but my Grand Prix is FWD. Does anyone have a 2.8 head I can buy? If a 3.1 will work, I need to buy a 3.1 head. If anyone has a head...

    How about a 3.8 in an '88?

    I like 3.8L engines. I have a 1996 Oldsmobile 98 that has the bulletproof engine and I love it. It has the ultimate compromise as far as power and fuel economy. After being chewed out all evening on another forum about wanting to put in a Cadillac 4.5, I have decided I would rather have a 3.8...

    Cadillac 4.5 V8 into '88 Grand Prix

    Hey, I found a 1990 Cadillac 4.5 V8 with 95k miles. I would really like to put this in my Grand Prix. My question is, will it fit? I looked up the specs on both cars, the Caddy is wider by 1 inch. Is this going to prevent me from doing the swap? It comes with the transmission, harness, and...

    Turn signal switch... bad?

    As can be expected on a 21 year old car w/250,000 miles, things will go wrong. One of these things is the turn signals. On my '88 coupe, the turn signal lever is the same one that does the high beam/low beam and cruise control. After getting this car, I have realized that you have to pull the...

    Where is the 2.8 forum?

    Hi, I know the 2.8 was only standard in '88 and offered in '89, but isn't there enough people out there with '88-89 Grand Prixs to have a 2.8 forum? If not, where do I post if I do have problems with my 2.8? Thanks!

    New from Iowa!

    Hello, I am 20 years old, and I just got my first Pontiac. As my user name implies, I just got a 1988 Grand Prix. Like all '88s, it is a coupe w/ the 2.8L V6. It has just under 250,000 miles on the original engine. That being said, one can expect a few problems. One of these problems is that it...
