Hi, have not posted before, but used lots of advice to bring my newly purchased 91 back on the road.
Ran fair when I bought it. 73,000K miles. Replaced the intake runner hose's with silicone, new plugs and filters, and fluids. Checked valves and timing belt, both ok. Cleaned out the gunk in the intake manifold and EGR passages. Cleaning the EGR got rid of the check engine light. New gas cap. Drove it around a 1000 miles or so to clean everything out.
Finally had to get the CA Smog to complete the registration. I tried to find the spout near the power steering pump, but it is simply not there! I did find the octane shorting plug near the transmission, so I pulled that for the 3 degree timing retard. Could not feel any power differnce, and no lights came on, so I went for it.
Passed: 114 HC .25 CO 700 PPM NOX @ 15 MPH
53 .20 710 @ 25 MPH
That is just squeaking by, but a pass is a pass. The HC is high at 15 MPH, and the NOX is high at both speeds. I may need to find that spout next time!
