Help!! Engine codes ...and misfires... When stepping on the gas in 4th the car seems to chug and die and then shuts off...now it has started doing it in 2nd and doesn't barely get a mile without dying...
we checked the computer and we found that e are getting alot of misfires...and on every cylinder when idling and when on the gas a little the number comes down...
This just started happening. It had been fine previous to this. The new engine has been in the car for about a month and we've dyno'd it, tuned it and raced it...it has about maybe 3-4k miles since the new motor went in. (422 LS6 heads ported metal intake (spacing issues were fixed before installation of intake))
We also have these codes although I'm not sure they will be of any help except the first one.
Another item...the Engine Sensor fuse keeps blowing. I have replaced it 3 times since we put the new engine in.
P0336 - Crankshaft Position (CKP) Sensor A Performance
P0155 - HO2S Heater Performance Bank 2 Sensor 1
P0801 - Reverse Inhibit Control Circuit Malfunction
Any help would be much appreciated.

Re: Help!! Engine codes ...and misfires... i know a messed up crank position sensor will make the car act funny and even make it die.
given the codes you stated , i'd check the harness where the crank pos. sensor hooks up and maybe the harness on top of the tranny .
sounds like you burnt through a wire or shorted it somewhere .

Re: Help!! Engine codes ...and misfires... well we replaced the sensor and it helped...but in doing so we found out that the wires which come down from the computer along the header on the passenger side had been burnt right through and 6 wires were bad...even though it had the protective foil around it ...so we fixed all that and put some heat shield around it...it's all working good now.
