i took my car to the track on saturday amd after 6 or 7 passes my check engine light came on random cylinder misfire was the code then when i left i noticed the torque converter lockup wasn't working i had the predator hooked up so i hit clear codes and it stayed locked for about 5 miles then unlocked again no check engine light but i cleared the codes and continued this every 5 miles on my was home i got home and check the plugs they looked good then i double checked to make sure the wires were on good and went for a drive and the same thing happened it would unlock the tcc and at a steady 3000 rpm you can hear a strong mis. i would like to drive it with out clearing the codes but the trans starts to get warm with out being locked up. any ideas
thanks blake..

 

any ideas please help

 

Stock cam?

 

There's a long list of possibilities for a misfire. You need to get it to someone who can diagnose it properly.

 

I'm guessing that 150 shot had something to do with it.

Try a compression or leakdown check.

 

You may have compound problems. Misfires will
inhibit TCC lock. A TCC that won't ever lock,
but gets better at every key-on and then quits
again may be seeing a slip code (P1870?), this
faults into a never-lock mode. But maybe you
are just misfiring full time, like the nitrous ate
a plug tip or something. I'd start with pulling
them and see. And do that leakdown or at
least a cranking compression while the holes
are open.

 

what should my car have for cranking compression

 

With a stock cam you ought to see over
130# I think; high overlap cams will be a
lot less. Key is more the consistency from
cylinder to cylinder, if one is way less
than the others it's got a problem.

 

crank sensor will cause random cylinder misfire.

 

Actually the crank sensor is used to figure
whether misfire is occurring, a failed crank
relearn or a flaky sensor can drive bogus
misfire detects. I don't think the crank
sensor plays any role in actual misfiring.
But it does, in the counts.

 

bent pushrod it was wierd it didn't making any valve terrain noise
