Today while leaving work my SES light came on. The tranny was locked out of reverse, like the car was off. I got it in by throwing it in really hard. It idled really low(around 800, compared to normal, which is around 1000. I hooked it up to a scanner and I got 7 codes. I don't know the numbers but the codes were:
1)Car running lean or rich, dont remember
2)O2 sensor bank 1, sensor 1, slow response(came up twice)
3)Same as #2 but opposite side
4)MAF or VAF not responding or something like that, don't rememeber exactly what it said(I have a ported MAF)
5)1-4 upshift solenoid malfunction

I reset the computer and they immediately came back on.

Please help, they all came on at once and I can barely drive it like normal.

Anyone ever had this happen all at the same time.

I installed some LT's a couple of weeks ago and the codes didn't come on for a couple of weeks.

Please help soon,
Ryan

Sounds like you burned the wiring on the headers.

I checked the wires and none of them are touching the headers that I can see. I need to put it up on a lift and check it out. That's the first thing I checked.

do you have a stock MAF?

It's a stock MAF but it's been ported. Been done for about 6-8 months with no problems.

replace the 20 AMP (yellow) engine sensor fuse. its in one of the fuse blocks under the hood. I had this happen to me also when my fuse blew when my MAF harness went bad. if it blows again then you need to look for the short. all the codes (reverse lock out, skipshift, O2's, MAF Frq.) you got those sensors are all running in the ENG SENS fuse circuit. so if it blows you will see the codes you have

Thanks for the help, that was the problem! Now I hope it doesn't blow again b/c shorts are a PITA to find.

Thanks for the help,
