I had the timing belt, water pump, radiator replaced at 131k, tune up at 134k and it has ran fine until now.

a few days ago i filled up my tank and was driving and i noticed that my gauge had gone down but the miles weren't in the norm.
it has now been 3 days and 151 miles ON a half tank.

So i popped the hood thought maybe I would notice a smell or hear something not normal. I didn't. Now i am noticing when i go down the road
it hiccups or sounds like it does. the idle pin on the dash doesn't move but it feels like is miss firing or something?

Any ideas? kind of frustrated with it:banghead: .
No check engine lights or anything, not running hot
just bad gas mileage and appears to miss a spark or something.


Thanks for any help
:tongue:

If it is an actual misfire, it will eventually trigger a code. The code will be P03XX. If the check engine light comes on go to Autozone or some other parts store that reads the codes for free. Record the code and then report the code back here. Then someone will be able to give you some direction. Also, you mentioned the mileage when the car got a tuneup, but don't say how many miles are on the car now. That would also be helpful.
