yaa well my car wont let me go past 50 mph :/! but i would try n get a buddys ecu and test theres and see if its any better. is yours a 5spd or auto

[muffler]

5spd, and the only person i know has a auto

Shaking at idle? Check injectors/spark. One dead cylinder will have that rockin'.

[Kwonza Says]

Ummm when I first bought my car I couldn't rev past 5k either. Try cutting the 5th gear sensor. That's probably telling you car it's in 5th gear topping out? I dont know try it out and see what happens.

hey try replacing the fuel filter if that dont work let me kno i meet up with you and u can use my ecu

[demonspeed]

Check plugs...my hatch had the same symptoms and lo n behold my sparkplug wire popped off

[Poppadoc]

yeah i dont kno y i said fuel filter cause when i had that problem i changed sprk plug wires, spark plugs, distributor cap, and rotor and that solved my problem

Well if it won't start check for fuel and spark. Pull the line off the fuel rail to see if your fuel pump is working. If you are then check spark. Then go from there.
