Default Ls2 running problems

Installed new ls2 in 1968 Chevy van. Got harness and ecm from swap specialties in ovid mi
Only running on right bank. Getting codes 122 and 342
Is there a place that work on swaps near Pontiac mi.
Swap specialties will not answer phone calls or sometime they will not reply to emails.

Check the cam and TPS wiring. Could have a wire or two mixed up there. What PCM do you have? P01? I can post a pin out so you can reference it if so.

Can you read the service sticker by chance? Part number? Do you have HP Tuners? Post a log? Sorry for the line of questions, but it's really tough to nail something down solid unless we know exactly what we're dealing with. Could be a P39, maybe a P01... I don't know since I always use the sticker/part number or tune info to confirm it.

Okay so that's the drive by wire TB... Did you check the wiring? I took a look around for wiring schematics, but it was late when I did and a few sheets to the wind at that point. My apologies there.

Talked to Turner today. He said to try cam sensor wiring swap. Also he questioned what cam gear I have. Will try to look at it asap. Thanks
