Rough Idle

[jimlam56]

Hi All:
Starting to get a bit of a rough idle.
80K, with Granatelli coil packs and new stock spark plugs replaced around 30K.
Haven't pulled anything yet to inspect, but would appreciate any thoughts.
Thanks,
Jim

Granasmelly coil packs? Not in my Marauder. Genuine Ford is more dependable. Take a close look at the coils and boots.

Clean the throttle body for fun and report back to us.

Hey Jim,

I have a complete set of OEM "take-offs".......they are fine but when we built the new motor I installed a new set I got from "Musclemerc"!!:beer:

You can have 'em free just pay shipping!!:beer:

I would try cleaning the MAF and IAC.

Thanks Guys, it's about time to do all of the above anyway.
Jack, thanks for the offer, I'll let you know.

And so was a guy named Dennis! They both failed in time! :shake:

Ugh, do you have a check engine light or a misfire?

Nope, just a rough idle.
I'll dive into it when I have time, my MM is a bit of a garage queen these days...

Clean the throttle body and go drive the car. :)
