hey whats up? first post!
my name is frank and i just bought a 1996 eclipse gs. when i bought the car i knew it had a rough idle but thought it was only a vacuum leak and a brake booster. well i replaced the brake booster and it still has a rough idle. i replaced the booster cause it had a hole in it. so after that i replaced pretty sure all of the sensors, coil pack, plugs and wires, and a oil change. now when the car starts some times it dont want to idle at all but dosent die then the rmps will stick between 2-3 grand, also sometimes the rmps bouce around. the car is running rich in all cylinders. when the rpms get very low the belt starts to scream. this motor is a junk yard motor i believe and the wiring job was done half assed. engine has good compression. im so confused!!!!! is this a timing issue? is this a electrical issue? some one help please!!!!
thanks! frank

Easiest thing is to log the car and read all the sensors...
