Just finished resealing the intake on the 88 GTA and the car is running poorly after the reseal. At low speeds 25/30 mph around 1000rpm the car will buck or kick under acceleration. before the reseal the SES light was on code 36 for the maf sensor causing the car to run very poorly but not buck and kick like it does now,clear the code and the car runs great no ses light, shut it off and the ses light comes back on for code 36. During the reseal I replaced the EGR valve with a acdelco one since i have had codes for it come up before but that was a while back before i decided to reseal the manifold. My best guess is the EGR valve is stuck open or opening to late or early causing a delay which causes the bucking at low speeds. My ses light is still on for the maf too which i dont think should make the car run as rough as it does. Right now i have no codes for the EGR only code 36 for the MAF. My plan is to unplug the vacuum line to the egr plug it and see if the car runs better I'm thinking about even possibly deleting it completely. Any advice or help on what i can do to figure this out would be would be greatly appreciated thanks.

 

If the code says "MAF Sensor", I'd be looking at the MAF sensor; not the EGR.

Might wanna take a good look at the wiring around it. Make sure it's plugged in good, nothing get damaged, etc.

Rule #1 of dealing with a "new" problem that appears right after you work on something is, Go Back And Check Your Work. It is NOT, Go Mess With Something Else Random For No Particular Reason.

 

"Deleting" engine systems with no clear cut plan of the modifications AND tuning required to actually produce any power gains is the #1 way these poor cars end up as hacked , badly running pieces of crap ! Yes of course there are considerable gains to be had with properly executed modifications , but when you are in the middle of troubleshooting a poorly running engine , this is the #1 WORST time to go "deleting" anything in the blind hope that removing parts is somehow gonna magically fix the poor running condition .

 

Makes sense if it aint broke dont fix it i shouldnt have messed with the egr it was plugged in but i wasnt sure if it was working correctly i thought something else could have been causing the maf code to trip Thanks ill go back and look over my work.

 

definitely dont want the car to end up a hacked piece of crap my goal isnt to gain power but get the car running correctly ill hold off on deleting the egr and look into the maf sensor since thats the code im getting thanks.
