Bribe your nearest senior forum member with pizza and beer to get a once-over second opinion. http://www.corvetteforum.cc/ubb/smile.gif

Jumper the ALDL pins A & B (upper right), count the flashes and come back with the codes.

I checked the codes 34, 51 bad MAP & PROM or could the PROM be causing the MAP to act funny?
|
87 doesn't have a MAP. Maybe you mean MAS?
When it does this, disconnect the MAS connector, and see if this clears thing up? (No fear, this action will set other codes.) Is it a stock PROM? Has it been removed from the ECM before? i.e. Bad connection. |
I reseated the prom same codes 34&51
|
Similar to what mine has been doing intermittently over the last few months (yes I am lazy). Except I only get a code 34 which, BTW, is low MAF. Most forum members seem to have cleared this up by replacing the MAF relays. I got a couple sitting on my bench waiting to go in.
