Spark Plug Problems

[jimberg]

Jeff, did you try your friend's MAF meter yet?

For those participating, I chatted with Jeff the other night in IRC and he said that he is getting a low voltage from MAF error when he reads codes. He also has stock timing, he believes, but needs to run 91 octane to keep it from pinging.

I told him to replace the MAF since he's getting a code for low voltage and it probably means the computer is running in open loop. Probably rich in open loop mode. I also mentioned that the front two cyinders get less air so will probably exhibit fouling symptoms before the others would.

O2 sensors have never been replaced as far as we know, so I also told him it was a good idea to replace those whether they were the cause or not, although they could cause a richening of A/F ratio.

He also got some fuel pump related codes, but fixed those recently.

I'm with Rick91GT as far as getting rid of the platinum plugs for Autolite 24s and gapping them at .053.

well thats what seperates the big guys from the guys who think they know.

Juiceman, everyone has a right to offer their advice whether wrong or correct. Slamming them because they disagree with you and are probably even wrong isn't really going improve the level of discussion or maintain the level of integrity that this message board has. We all have our level of experiences with issues we have encountered and are willing to share them with people who sound like they have similar issues. Maybe they apply and maybe they don't. It's up to the reader to sort it out.
