Did you pull out your dizzy? You might want to check you timing and make sure all of your vaccum lines are connected.

what kind of exhaust do u have could be a plugged cat if you have them

Alero99

check TPS EGR fuel pressure ect ect.

i have a very similar problem but mine only starts to occur after the car gets warmed up

my dizzy is off by a bit i have to pull it and install it the right way

i just put brand new cats on it so it cant be the cats and the timing is dead on i already checked that

is your MAF Straight up and Vertical? NOT LEANING LEFT OR RIGHT, even a little bit?


Did you tighten your lower intake with the torque spec procedure?

blackknight1456

no its an 87 it doesnt have a maf so thats not a problem at all

so your timing is dead on??? sure the balancer hasn't spun a little making you think your timing is dead on when actually it's not?? just a thought

Kinda sounds familiar doesn't it Mjr lol. Pull off your dampener and set the key in the crank at exactly 12 oclock and see if you are still on plug #1!. Thats what I had to do just to find out my TDC is at 30 deg on the balancer at the moment.

Timing is off.
[ul][*]Disconnect the coil wire.[*]Pull the #1 spark plug[*]Have someone bump the starter while you hold your finger over the hole[*]Once you feel pressure stop and look at the pointer over the balancer[*]Remove dizzy cap and verify that the rotor is right at #1 plug wire.[*]If it is not you will need to turn the engine back or forth at the crank and reinstall dizzy.[/ul]
