Thread: Gp problems

Hey guys I'm having a issue I have a 98 Grand Prix GTP stock and it's been ok until now well recently I did both control arms and the next day i noticed while driving on the expressway any were from 50-75 or trying to accelerate lightly the RPMs drop and the car starts to shake or flutter like a misfire until I let my foot off the gas or lightly press the brake then it goes back to normal just for a little bit & as far in street driving it does it after 35Mph i haven't had a clue what's going on I don't know if its the trans or engine any ideas

If he only messed with control arms his alignment should be unchanged.

new ball joints and bushings can and will make the alignment off. the steering wheel was off a few inches when i changed mine.

how its running is unrelated to the lca swap. try a tune up if its not been done.

If you haven't already, check your trans fluid level (at operating temp, on a level surface). Top it off if it's low, then do a pan drop/filter change when you get it home. Before cleaning the pan up, get some pics of what's in it right after you remove it and post them up here. Also make sure your battery terminals are clean and tight (same way I like my women), corroded terminals and/or grounds will make the trans do funny stuff.
