Asked by Sincere Nov 01, 2015 at 08:20 PM about the 2004 Chevrolet Impala

Question type: General

When I drive sometimes my Chevy Impala 2004 will do little small jerks when
I'm pushing the gas-what could that mean.. Like I said but not all the time and
sometimes I'll be driving for a while it won't do it at all then if I cut it off go
inside the store get back in and start driving it'll do it out of nowhere?

Could be cutting out due to a bad coil, or coil packs, have it checked by a analyzer that can show live data. This should pin-point the issue.

I have an 04 impala and mine is doing the same thing, and I've noticed that it usually does it running at full temp. The speedometer needle is also jumping up and down. Changed the maf, no difference. I'd like some ideas before I end up changing all sensors please
