Hesitating/missing while driving on the interstate. Bad gas, spark plug, fuel pump???

"jayman" offers a great suggestion. Are you receiving any warning lights? If you PM me the last 8-digits of your VIN, I would be happy to look into this further for you.

I look forward to your reply.

rockmurf,

Sounds just like my car last summer, got new coils, problem persisted, there was a recall on my cat converter so they changed that, problem persisted, said with no lights on they couldn't do anything. So it still does it now. :(

What about changing the fuel filter?

get the codes read. even if the CEL is not on a code may be stored. I bet it is P2135 TPS. ask me how I know? Then look at my screenname.

If no codes at least try cleaning the throttle body before spending money on coilpacks. it is not the plugs so don't waste time.
