I got a level 4 transmission and 3.42 gears and now my check engine light flashes and it is missing badly.

I had checked injectors, Plugs, Plug wires, and coil packs

I scanned the computer and it says "random missfire on multiple cylinders ?"

My GF took it to the shop for me and they said their scanner shows the # 8 cylinder is missfireing ? WTF happend here ? Bent Push rod ?

Any help would be great !!!

Try switching the #8 sparkplug wire with the #6 wire and see if the problem goes there. A plug wire might have gone bad.

SpinMonster

get new plugs and wires

Another thing you might try is checking the connector to the coil. I'm pretty sure you can swap coil packs. You could try swapping coil packs and see if it switches sides. I wonder if there is a bad optispark? If it's not ignition you could have bad A/F. Maybe a bad O2 sensor? You've got to isolate it to one block of components, then go from there. You said you checked the injectors, what about the connector on the injector? :confused:

Well I know it is not the coil pack I swapped that last week and it is not the plug or plug wire it is not he injector i swapped it .

I am still leaning toward a bent pushrod ?

Auto tap says it is on Cylinder 8 but we have tested everything but pulling the valve cover ?

You have reason to suspect a bent pushrod? If so, it may be the problem, or perhaps, part of it.

Compression check?

All the best. :yesnod:

Yeah an over rev right befor the missing
the cyl has 180 psi compression

How can you over rev when you have a rev limiter ? I have been into my limiter many times and no problems. :)
