-12 tonight on the drive home, truck started shaking weird, when I stopped at a light it was shaking still like it had a huge cam, it didn't necessarily want to go when the brake was applied but just say there kind of idling weird and shaking the whole truck,didn't stall at all, kept doing it the whole way home, felt it less in overdrive, it's similar to the shake I get when going up hill in a higher gear, nether the less it's still a problem, I'm thinking coils, maf, or tranny

 

I had a similar issue about a year ago and it turned out to be the MAF. I replaced it and everything was golden.

 

clean your maf and iac. An look every where for vacc leaks. No codes? Also does it do this in neutral?

 

Had a really bad shaking problem recently in my 98 4.6 when accelerating and idle, turned out to be bad spark plug wires, I'd still recommend a throttle body clean up and clean maf sensor as I've seen they build up a lot of carbon in the throttle body.

 

haven't tried it in neutral, I cleaned my tb this summer I'll try replacing my maf, it happened last night I'm heading to work soon let's see if she does it again

 

Ended up being a bad coil, cylinder 6 was mis firing, changed coil,plug and a vacuum line leak runs good as new
