I'm Awesome
Hi yall,
I recently rebuilt my l29 vortec 454. It runs well and cleared emissions checks.
Last night while driving on the freeway I lost power for 2 seconds, as if I had let off the gas, then came back and I kept driving. I shut the truck off for about 20 min, came back and I had a check engine light.
I tried to start it but it would only surge rpm then shut off. I tried again 5 min later and it ran without any issues.
I checked fuses after researching and found Eng 1 was blown.
I replaced the fuse but can't see anything that would cause it. I checked the o2 sensor wires and they look fine.
Here are the codes :
P0301
P0340
P0102
I'm guessing one might have caused the others?
Anyone ever have this issue with all these codes? Is there a way to troubleshoot the maf without a GM tech 2?
Thanks for amy help!
