Subject: Re: Spark Knock is back.... and I figured out why... And it's BACK AGAIN!!!! by bogus on 2011/10/25 5:31:24 Just got done about 40 min ago... had to clean up, take out trash and take shower. It idled for about 30 minutes... so far, so good. Before, as soon as it hit closed loop, it would take a dive. Exhaust manifolds are a BITCH to do... so many layers of parts... From all 8 plugs, wires to the AC compressor and alternator bracket... However, new plugs, newer manifolds, new copper gaskets... used anti-seize and lowered the torque accordingly. Spec says 26 ft-lb, I did 20. Same with the plugs, 18 ft-lb, I did 10. No codes... but I still suspect the fuel pump isn't doing it. The pressure is at 40, and I remember setting the AFPR at 45... it does rise when you hit the throttle, but only 2 psi or so, vs the 4-5 expected. Let off, pressure drops below 40. Otherwise, it seems to be running fine. I will report more tomorrow after I drive it. |
