Hey all, 91 GTA 305 car with 350 swap. Hypertech piggyback and k&n filter directly on the throttle body.

8 years in storage is a fair bit of time mate, pull the codes from the ECM - start from there

for someone who had this issue... i cant believe i forgot about the cat.
If the cat is hollow or bypassed, check the muffler, mine was full of about 6kg of fine black soot.
