Ok, so heres the deal I did a 92 DOHC zc swap in my 1990 dx hatchback. And, she purrs like a kitten. I only have one error code on the PR4 ecu I'm running which is a code 10, or the intake air temp. I just gotta figure out where its at. But now to the real problem Yes she purrs like a kitten, and has 180 psi compression on all 4 cylinders. But she is sending white smoke out the exhaust like there ain't no tomorrow. My neighbors thought the car was on fire. Any ideas?
