Excellent info guys we will work on checking the Weirdness.

Here is another little-known factoid. The PCM has a table for injector pulsewidth vs. voltage. If the voltage is too low, the pw is going to be off-kilter.

Ok here is the list of numbers and I went all around under the hood with a can of carb cleaner and found no leaks. I did find that the O2 held on rich when held at 3000rpm. The last time I scanned it it would hold lean when you bliped it to the floor. It also has a exhaust leak and pops when it decelerates after a rev and I am not sure where the leak is. The voltages as far as the scanner goes stayed at right around 13.0. There are no more codes either. Let me know what you think, and thanks again.

Idle

LT Fuel Trim - 131
LT CL - 16
ST Fuel Trim - 128
MAF - 1300-1450
O2S - 600-650
O2 Crosscnts 48-52
20 degrees of timing
TPS - .035

Holding at 3000RPM

LT Fuel Trim - 110
LT CL - 13
ST Fuel Trim - 92
MAF - 7000-7300
O2S - 879-884
O2 Crosscnts - 0
31 degrees of timing


TPS fully opened 4.10

hay guys check the post above if you may have an idea on how to help out...thanks

come on guys no body has anything? please someone just look at it...(post above) i just dont want any body to for get about whats going on here...i realize that there is a lot of people on here but i guess i just trying to get noticed

Idle looks fine. The PCM is trying pretty hard to lean it out when you have it at 3000 rpm. 128 is the target for the trims. Lower numbers means it'* rich and trying to remove fuel. Higher means its lean and trying to add fuel.

so do you think the PCM is bad?

I don't know. I can think of a dozen ways to address a lean condition. Not much for rich. The ST being so low at 3000 rpm would suggest that it'* still learning. Have you changed anything recently and not driven much?

I thought he swapped the ECM but I know he drives it every day to work but his work is close by. If it is leaning out at 3k wouldn't that be a clue to the fuel pressure drop?

i have changed a lot of things...look back on my post and you will see....somebody asked the same question in an earlyer post.
