Has anyone had a hei module on the distributor go up? what symptoms would it cause, i have a suspicion that is whats wrong with mine

 

Misfire at high-RPM, misfire or cutting out when hot which resolves itself after cooling down, no spark...

 

That describes my troubles perfectly lol should I attempt a new module or a whole new distributor? Which would be be easier and or better?

 

I think autozone tests modules for free, also check wires, coil, cap + rotor, spark plugs first, its free to check and cheaper to replace. Also, my coil on my s10 truck had a crack in it and it would act like your describing when it rained or was humid out. Don't spend your money right away.

And changing the icm would be easier than changing the whole distributor. It just some wires and bolts to get to it. Good luck!

 

Krazyfirst that engine compartment looks sweet.

 

Thanks, it still needs some work, the inner fenders need painting, the accessories will be polished, and new or I might repaint the valve covers. But thank you very much!

 

to just replace the module is by far the easy and cheap way out . be sure to use the grease supplied . it acts as a heat sink/transfer , without it new module will last real fast . good luck .

 

Thanks guys for all your help i will try the module next, everything else is new so that is the only thing left to go bad i guess lol just hope it fixes it cause i wanna drive! i just swapped a 5 speed and put headers on it so it should be nice if itll stop misfiring haha
