Engine Performance problem 4 cyl Two Wheel Drive Manual
I just rebuilt a 2.2l in my employees car. Engine timing marks were on the nose and dialed in for #1 top dead. When we fired up the engine it acts like the timing is advanced a tooth as the motor shudders/shakes heavily while it runs. I know that the timing gears and chain were dead on at assembly. I also now that if the timing was retarded a tooth we would get popping and sputtering out the pipe. We have none of that. There is no mechanical noise when she run but the shudder is very pronounced. There is no distributor on this, instead there is a cam position sensor. Also the check engine light flashes red. I can not find anywhere to adjust the timing on this engine. I am a seasoned mechanic and it feels like the timing is roughly 15-20 degrees advanced. Its like the engines fires on the upstroke and the combustion tries to stop the upstroke of the pistons. Not enough to stop it from running tho. Can anyone tell me how to adjust the timing on this vehicle. I also got the plug wires running 1, 3, 4, 2 with #1 being closest to radiator. Thanks for any advice you can give.
I currently dont have a code reader. And it doesnt appear that the blinking check engine light is flashing and sequences. How do we proceed?
have the same problem?
