go to an autoparts store and have the codes red for you. Just because the the service engine light isn't on doesn't mean it's not throwing any codes.

My Service Engine Light didn't come on. I had a bad coilpack & did the tune up thing. I also had a fried MAF sensor.

jimfash

how did you find out it was fried?

Once the tune up was done, she was still running weird the mechanic decided to check the maf, low & behold that's what it was. She runs like new now.

It can also be your IAC valve. Its the cylinder looking thing bolted to you Upper intake plenum. Try taking it off and cleaning it with either carb cleaner or brake cleaner. Either one will work fine. The IAC valve is what regualted your idling

ya i've used that spray before, worked like a charm

possibly change your plug wires...
I noticed a slight stutter under accel in my car... found out it was a bad plug wire not making full connection... FRPP 9mm wires went on to replace them
