HELP! Supercharger ???'s

[CONRAD II]

Hey Gay bob stop reading my post your arse. If you were not such a prick you would have something better to do. Go sit on something with AIDS and spin!

Taz and Obz thanks for all your help. I got my truck back and the shop said that the oxygen sensor had come loose, causing the check engine light to come on. Also, they had to change some programming in order for the volant maf to work proper. I drove it about an hour today to the country and it never varied much below or over 14.5 on the af gauge. I know that my gauge reads lean to the right rich to the left. My tuner told me that variance is normal though. On the way back tonight I averaged 14.5 but under throttle the number usually dipped some and sometimes when I backed off the gauge would read up to 16 but never stayed for more than 3 secs and dipped instantly when I gave the engine some throttle. The truck ran great the entire time and my check engine light did not come back on. Am I still in dangerous territory? Am I being paranoid? Dose the problem sound solved?

Also sitting in idle it almost always at 14.6. But my gauge is always going back and forth between up and down usually rich for the first few secs after boost as it speeds up and ramdomly will seem to peg 16 but almost always under little throttle or coasting at speed. Cobalt makes the af gauge. Again, the truck seems to run just fine the whole time all this stuff is happening and no more check engine light???? Also it always only reads lean under vaccum not boost. The saga continues...

The only time the af guage is of real importance is at WOT. The rest of the time I would not worry about it much.

I run a light system and I have a switch in line to cut power as the lights run up and down blue to red under normal driving. So unless i know I'm going to be in a WOT run I have them turned off. Boost gauge and fuel pressure gauges stay on.

Awesome I'm glad your on line! So why is there such variance, is it just the gauges showing compensation for vaccum vs. boost under normal driving conditions? Another weird thing is that my gaughe is wide band and red/lean is on the right and rich/yellow is on the left. It also gives the ratio 14.6 etc. Most of the cobalt gauges i've seen are the exact opposite. I just hope I finally get to start enjoying my charger instead of waiting for the engine to grenade.

You got the idea. Plus it is just af jumping around at cruise or slow down so the vacuum sort of mirrors that.
