HELP! sputters and dies with occasional backfire
This has really gotten me frustrated. I recently took the car down to pull the supercharger, switch back to NA intake with AFM and do a ton of suspension/brake work.
Now, all is back together but I get a 'starts then dies' from it. Random backfire through the intake and exhaust. It's getting spark and fuel. The fuel in the rail is sitting at 42psi, cap and rotor are tight and fine, plug wires are good, coil was working prior to downtime. Unplugging AFM yields the same symptom. Grounds are good. TPS is adjusted properly and known to be good. DME relay is good. Vac lines are new and good. Any ideas? Have I narrowed this down to AFM or AFM harness?
Thanks,
jp
