Lt1/t56 stumbling under load

[blank94z28]

Hey guys and gals, I have a 94 camaro I recently swapped engine, pcm, harness and trans in. It was an lt1/auto car and I swapped in a freshly built cammed lt1/6speed combo out of a wrecked 94 camaro. The parts car also was previously an automatic and was turned into a 6spd car. My Car now has a stumble after it reaches operating temp. I have replaced all of the following:
Opti
Plug wires
Coil
Icm
Fuel filter
Fuel pump

Car has a ses light on but my scanner wont link up. And the scanner worked before the swap. Is it possible if the pcm wasn't tuned for the cam it would cause this problem? The guy that built the motor said the pcm was tuned but I don't believe everything im told when buying used stuff.

Any help is greatly appreciated! Thanks!

since you are not stock it could be anything.....

when you replaced the opti what brand did you use?

I believe the opti is a cardone new unit. I know it's no msd but its what was in stock in my area and has a lifetime warranty.

If my pcm was not tuned for the cam could that cause all this? I bought the parts car and it had the cam installed already and it idles at 1000rpms and lopes pretty good.

Big cam+no tune=car running like crap?

You need to know what the code is

Tried 2 more scan tools today with no luck.

Also just found where my vibration is coming from, the balancer is wobbling all over the place at idle, when revved up a little it seems to straighten out but its bad at idle. Could that be causing any other problems?

Here are the codes and readings at idle.

Code 22 tps sensor low voltage

Code 44 left o2 sensor bank 2 lean condition

Code 97 ignition system 4x sensor circuit problem.

Injector pulse left-4
Right-0

KS count 1920

KR was 3-4 at idle 11 at 2700 rpms

Open loop maf gr/s 8

Map "hg-17

O2 left bounced between 20-110
Right was a steady 480-500

Spark advance was 17-20 at idle

Lt fuel trim cl-16
Lt fuel trim l-160
Lt fuel trim r-128

I would say you need a tune.

I would say you need a tune.

I second that one

Send the PCM to Frost. It is the best 150.00 you can spend.
