I got a 1996 Grand Prix 3.1 litre V6
Just recently i got my intake manifold casket replaced because it broke and coolant leaked into oil.
Clean all the gunk out and but car back together engine fluish oil change etc.
Car was riding alright for about a week before I noticed few minor changes.
On way home from work i hit an intersection going left slowed down and as i accelerated past 2500 rpm the rpm kicked back and car stalled..
turned back on no problem drove 10 blocks and this time only going past 1500 rpm car kicked back and stalled.... had trouble starting but let it cool down and drove good or atleast good enough to get home
Next day drove around the block..good for about 10 minutes than all over again..
Tried changing fuel filter not the solution...
no lights turn up for check engine or anything as im driving
oil is at good level...clean
maybe fuel injectors or something electrical that i may have not done while putting the car back together any help please lemme know so i can give it a try.....
