Default Plugs fouled
Now my other car is running like crap
Pulled plugs all black and wet with gas.
Missing and when I try to up rpms it backfires
Could this be from a bad Holley power valve?

Maybe but unlikely. More likely a stuck needle & seat.

Check all of the above......let us know what solved the problem.

I am hoping it is one of the above.
If it turns out to be something else out comes the credit card again.


Anyway now power valve is in and so are the new plugs.
The distributor is a one year old MSD with a 6Abox.
I think I will pull the cap off the distributor first and take a look before I start it up.
Wish me luck

To check the power valves screw the idle mixture screws in if the engine dies there good if it doesn't then there bad.

Wish I knew that before I bought the new one.

Anyway I hope I don't wipe out all the new plugs when I start it up.
Was major pain putting the last 3 in

Be advised that you may get worse mpg using the power valve delete-"plug".......ask me how I know...LOL.

A bottle of Lucas Fuel Treatment in a tank 1/2 full of gas will clean up sooty spark plugs!

Problem solved
2 things were screwed up
First one was a bad power valve in the holley
Second one was a plug wire touching a throttle lever and grounding out

Car runs great now
Thanks for the input
