It drives like ****.. Ran sea foam. Changed spark plugs and wires. Changed oil. Flushed the coolant. Flushed the Tranny. Done a lot but it's like it hesitates on the throttle a little, It's slower and it's not bad but enough that I wanna trade it in.. The transmission shifts ****ty every now and then.. The only thing I haven't replaced is the fuel filter.. Ideas??

 

what about the air filter

 

A bad MAF sensor or vacuum leak can cause both of those problems.

Hmm, perhaps the cat. in your exhaust might be clogged up a tad? Would cause a nasty feel to the engine.. has it been sounding any different as well?

Those are the three spots I woudl start... MAF, Vacuum, and then cat.

 

I'm going to go with MAF as well. Try a bottle of Red Line SI-1 fuel system cleaner - I've found it a lot better than Sea Foam in the tank!

 

I have replaced the air filter.. How do I figure out if it's the cat?? MAF?? M?? Air Flow?? I'm gonna go clean the throttle body and the IAC vavle, now.

 

if your fuel filter is clogged up it might lag in getting enough fuel if your doing quick starts.

 

It was the MAF and I ended up cleaning the IAC and the throttle body and all the wonderful ****. Feels a lot better.
