Not the wires or plugs. I'm stumped right now. Does anyone think that the balancer could cause these symptoms? I dont want to go spending $150 on a busted motor.

By the way she is running now. Dont know what happened when my wife was driving her.

For a recap I've replaced the Ign module, coil, wires, and plugs. She has a strong odor of gas coming from the tail pipe, and it sounds like she is spitting out the tail as well, and absolutely no power.

What about the EGR Valve? Have you tried pulling the exhaust to see if the cat is the problem?

Obviously it isn't ignition related. And if you pull a plug, is it wet with fuel or anything?

plugs had a little carbon on them but not too much. No oil no gas. I cut the Cat off first cause that'* how it feels, like the exhaust is plugged. I'm gonna pull the muffler and fuel rail today.

Drop the whole exhaust [isn't hard], and run the car with just headers. It'll be loud, btw .

Not the exhaust. Autozone loans compression testers, I think I'll go get one.

Not the fuel system. I wonder if an exhaust valve is busted? Anyone know how to check?

Compression fine. 155psi on 1,5, 150psi on 3,2, 145psi on 4,6. Book says they should be over 100psi and above 70% of the highest. By the way we need the 14mm long adapter on the compression tester.

Any other ideas? Maybe ECM? Maybe crank sensor/ pulley? What are a bad EGR symptoms?
