Tapping on the MAF sensor did not change the way the car idled. I tapped on the MAF sensor after it had warmed up - which took a while due to it not wanting to run correctly. The codes did reset but the MAF test didn't really show much. I ran the car today so that I could try resetting the codes and mess with the MAF sensor. CC on the scanmaster is 'O2 sensor Cross Counts' which is a reading telling you how fast the stock o2 sensor is cycling between rich and lean.basically if the numbers cycle from 0-255 in ascending order while idling and cruising warm.that is normal.if they stop or show 0.your 02 sensor is dead If it's misfiring, it won't really give you an engine code.Ĥ. If the MAF IS good (which I doubt).you could have a bad coilpack (back of the motor). If not then don't worry about anything except the MAF sensor.ģ. Look at your scanmaster after you start the car up again and see if you get any mal codes showing. You want to reset the computer so it has no codes showing. Try unplugging the orange wire by the battery for 10 seconds, then replug it. Wow that made the car run so much better.Ģ. Trust me I know.I went through 6 of them before I got fed up and went the LS1 sensor route with a translator and then I went MAFless with the translator Pro setup. If you let the car warm up idling, then tap the MAF sensor with a screwdriver, and the idle changes, it's bad. If it skips around while driving, it's bad. Might want to check your AF reading during cruise. The stock style MAF sensor CAN be still bad with no engine light on.

This year looking to rebuild stock turbo, change spark plugs from ac44ts to ac- delco 43.1. I ordered it from Turbotweak, I have TT 93-94 octane chip in the gn now with matching 009's, 340 pump, hotwired, Acufab reg(43psi), 17psi, hooker, stock downpipe,turbo, IC, stock MAF sensor, rjc PP, rjc BC, 160 t-stat, new body bushing, kirban rear seat brace kit, 25psi/vaccum, water gauge, rebuild trans/rebuild & mod stock convertor, rear main seal replaced with trans, no alky, besides the air cleaner looks original. I should already have got this scantool 2.1 a couple of years ago. I hope it works like it should, looking forward to reading the car. I'II find a good ground somewhere.Just to keep it stock later without cutting any wires in the car.Thx again. I would rather use a connector plug (from the store) to join onto scanmaster wires for the power(IGN) and ALDL plug (pin E). Thx everybody for the feedback.The pics help me out greatly, To see installing the scantool 2.1 correctly.
