Car is an '85 GN hotair.....
I have an awful popping / missing problem - hence my other post.....in Hot Air forum.
I currently have AC Delco R44TS plugs gapped at .035" installed.
Are these correct ????
See below :
Car sputters and pops heavily under load but not in idle. Cant drive her like this.....
I have:
-new AC Delco plugs, R44TS gapped at .035"
-new GM O2 sensor
-new 87 GN coil and IGN module
-new 8.8MM plug wires
-stock chip and ECM
-FP set to 32-35 PSI at idle (lvac line off)
-using 93 octane gas
Jeremy (NOCOOLER) sold me an 85 ECM with a Pitbull chip in it. Should I try that ECM/chip or try new plugs ? Could my stock chip be toast ?
