quick engine question?
I have a 99 Yukon 4dr slt its just starting to show signs of hesitation on hard acceleration , this has been getting worse lately ,, I think its Time for a new Fuel filter?
drives normal other than that |
Any check engine light or codes?
Does it only happen at certain times, ie. hot vs cold engine, only when it rains, etc. Filter wouldn't hurt. Might be plugs and/or wires too. Gary |
Nope wires and plugs were fine 6 months ago no lights
I think its the filter or the electric pump, feels starved on hard acceleration, if you back off the pedal it starts picking up again, ill throw it on a snap on computer saturaday and check the pressure, miles is about 55k |
Dirty injectors?
|
That should have been:
Dirty injectors? How's idle? |
idle is great runs fine , you would not know unless you punched it
to pass, worse in this colder weather, I know colder means more fuel, |
Try the filter, it's cheap and easy.
|
My money's on the the filter.
|
Not easy in this cold :D :D its like 8 degrees and my buds garage is busy today so no lift:(
|
We just started a warming trend here in St Louis. It should be on it's way to you this weekend. You'll still need to wear your mittens though.:p
