Thread: 98 GTP with a crap lot of problems!

Ok so my dad decided he wanted a car exactly like mine (I have a 97 2 door gtp) so he went out and bought a 98 gtp 2 door coupe. Well needless to say he brought it to me from TX all the way down to AZ for me to fix, it has a crap lot of problems which I need everyone's help with(I know I could search but I dont know where to start)

So here is what I have done and then Ill list the trouble

I did a whole LIM gasket replacement with tune up new vacuum lines , valve cover gaskets, new starter ,new power steering pump and Antifreeze flush to green stuff

Trouble

1- Car seems to bog on acceleration , when I try to go WOT the car wants to stall , power seems to fade.

2- I replaced the starter with a new one and I get a clicking sound (click, click, click, till it starts .... sometimes it takes a while) I took it to check the battery and I was told its good (12.9 I believe that's what I was told)

3- A/C blower was working fine through all vents before I bled the air of the cooling system now I don't get air through the main vents only the lower vents. I also have a bunch of plugs not plugged in on the passenger floor side by the blower ,I posted pictures on another thread about all the plugs that were loose I still dont know where they go I could see a vac line on passenger floor also which is not plugged in ( http://www.grandprixforums.net/need-...ugs-81022.html )
. The vacuum line that goes around passenger strut area of the car was removed so I ended up capping the accessory vac port on the supercharger , any help how I could find this would be appreciated

4- Just got new tires an aligned the car and it has too much play on the steering wheel , how can I fix this

I should've kept my dad from buying a car with all this problems but now im stuck trying to fix it any help will be appreciated!! Thank You

Alright..let's settle in....and if we can, keep this to this thread. Second and third threads on the same thing get confusing.

1. Bogging, this sounds vacuum leak. Did you do the TB gasket and cleaning? Did you replace the injector o-rings, have you sprayed with TB cleaner to find vacuum leaks?

2. What do you mean click click click click, we need more info. is this a noise while the motor is turning over via the starter? Is this an interior noise, is the motor being turned over by the starter? Did this noise exisit before you changed the starter and after the lim, before the lim..you get the point.. detail it out please.

3. Put the two big connectors together. That's an inline for I think the Hvac system. The little connector looks like a blend door actuator connector, really it looks to me that a novice changed something under there and didn't finish reconnecting things. Hook that vac line back up too. Now the vac line under the hood.. find it.. fix it .. rubber vacuum line is fine. That's the vacuum for the dash vs vent vs floor actuator. No vacuum...no control. Fix it up.. hook it up.

4. Check your tie rods, steering rack to subframe bolts, wheel bearings and all the other suspension stuff. If you need more info on how.. please say so and someone will hook it up.

This car doesn't sound so bad.. it's a 98 and w/o normal maintenance or someone that knows what they are doing.. things can get behind. Doesn't seem all that bad to me.

Ok first of all THANK YOU Bill!

Here are some responses in regards to your answer

1- It seems that the car has a northstar throttle body, I didnt change the gasket when I reinstalled it back after LIM replacement, I still need to clean the throttle body. I do hear a "hissing" sound going from the boost bypass valve in front of the supercharger to the vac tree on top , maybe thats the problem?

2- The clicking sound is before the engine could turn over. Seems like the starter solenoid is not engaging. It has a new starter and it also did this with the older starter that the reason why it was replace. Maybe it has bad connection?

3- Is there a diagram where all those lines hook up to? I tried connecting the big connectors and they wont connect.

4- All the suspension parts where checked when I took it for the alignment. I was told everything looks good , does the steering wheel column have a part that gets worn out after a while that will cause this problem?

Thanks again for the response and help ..

hiss sound means vacuum leak. Check the intermediate shaft.

Ok.. we need pics of this engine. Just one or two from in front and general pic. Then we'll be able to help further than guessing at which parts you have.

1. If you hear it.. fix it.

2. Pull the starter back out and look at the teeth on the flex plate.. turn the flex from teh crank bolt or at the flex with a screwdriver to look at it all the way around, how many teeth are missing?

3. I'm logging into photobucket..anyone that's been in my pb knows it can take a min

4. not usually. Don't trust them. Do it yourself and usually they won't check rack to subframe bolts.
