Well i think my engine is messed up now because when i start to rev it up.. it missfires at 5000 rpms on most gears.. mostly the high gears.. like 4th or 5th. It was never like this until I got my car serviced, Changing timing belt, water pump, spark plugs.. those kind of stuff, and after that, my car was all weak and miss fires and lags.. i mean I lost to a civic on the high way cause my car maxed out at 109 MP ! i used to be able to go to 130 mPH! I was thinking of engine swapping into another 420a because of this. I was wondering if any of you guys know anything that might have caused this. I was thinking he timed it wrong or something. but i'm not sure.. it idles at 1100rpm right now on neutral and goes up and down between 1k-1.1k rpm. Thanks

why don't you take it back to where ever serviced it and tell them they fuct it up?

see thats the thing.. the place that did it shut down and iono where they disappeared to.

have you checked your plugs and wires? when mine misfired along time ago, i had them looked at by my uncle, (back when i knew jack shit about eclipses) and he said all i need is new plugs. so i changed them and the wires and all was solved.

DarkOne> but we all have that inner ricer that is just dying to come out sometimes...

check:
spark plugs (GAP ESPECIALLY), plug wires, your coil pack (make sure it's re-secured to the valve cover and the connection is tight), also look around the bay for anything loose, missing, or broken. If you have more problems, look into getting a used coil pack from someone to see if it works.
