Noted that many were having issues with screws, etc. The advice to tap the screw head thru a screwdriver was essential for me. My screws were not budging even with visegrips and high torque screwdriver combined until I tapped them. However I did add one drop of xxblaster for my final try. I literally snapped 2 screwdriver heads (insert type - potmetal?) trying to remove them. Instead of a steady pull on the visegrips give it a snap (old sailing trick). The visegrips also were great advice. Thanks for all the helpful tips on this site. Couldn't have done it without you.

Can you describe the issue you had with the re-installation? I am having the same issue on my end, but I didn't remove the valve body, I did the short cut fix. Thanks I had the same oscilating issue. I had put the Black Coil upside down. See my post under SC_owner.

To GoldenStateSilverSport Thanks for the detailed (w/pics) instructions on IACV clean out. Just completed, worked great. Solved my prob and saved me several hundred bucks I'm sure. Note to users of these instructions, it is possible to put the Black Electric Coil in upside down be careful there. Caused my engine to idle rapidly oscilating up and down between 2000-2900 rpm.

I assume you have already bought but I will add this for anyone else following this link: 92 SC300 with 289,000. Bought 8 yrs ago at 173,000 for $3k. Up to that point only had valves adjusted when new, oil changes, brakes, etc. But had slow main bearing seal oil leak (quart per 3k miles) - didn't fix it. In 8 yrs only cleaned fuel injectors once, ran regular gas, never officially changed oil, used Mobil 1 oil. Current condition: A/C has lost charge, speedometer has lost 1/2 of it's lighting, and 1 muffler has hole. Basically I have neglected the car yet still had little go wrong with it: however, I would drive it coast-to-coast tomorrow. I drove it 140 miles per day on interstate for 8 years. 2000 ES300 with 212,000. Replaced oxy sensors several times, ECU, couple of electronic control components (can't recall which at the moment), brakes/rotors, oil, etc. I just put 30k miles on it in the last year.
