Im not sure if this is the correct place to post this but I will give it a shot.
I have a 98 Trans Am with 94,000 miles the mods are in my sig.
The problem I am having is when I stop at a red light the car starts to missfire and the oil pressure gauge starts radically changing from a normal psi to a lower one. And ocassionally shuts off.
I took it to a shop by me and they checked the
ignition coils all are working properly
spark plugs all gapped correctly
fuel pump tested fine
did a leakdown test and it tested great, good compression in all cylinders.
tightened the springs only one was barely loose
Im sure im leaving something out Iwill have to check the receipt on what else they checked.
But after many man hours are $1,100 later it still does it, not as bad but def. noticable and really annoying.
Do any of you fellow members have any idea as to what else it could be?

I also do have a full dyno tune, and the shop that did the tune did this work on the car too.
