Thank you for providing this valuable information! Helped me identify malfunctioning egr valve on my '88 4.3 vortex v6. I bought truck that had new spark plugs and wires, fuel pump, fuel filter, exhaust manifold gaskets (donut"s). I replaced corroded distributor cap. Don't get a code besides 12 now but engine light comes on at a quite predictable length of running time. Not as much pep or power as there should be. Also will bog down at times and hesitate to varying degrees.

When I try this the engine service light doesn't come on. When I turn the key to the run position it turns on and then immediately switches off. Also if the engine is running the engine service light is constantly flashing. I have a wire on the two spots that you showed in the video. Do you have any suggestions? Also the low coolant light came on after I did this but it's just a solid light. I have a 1995 Buick Roadmaster Estate if that helps.

OBD1 is a lot less finicky than OBD2, I remember my 94 Econoline 'clearing' the mass airflow code when the van was turned off, and only illuminated within seconds, and repeated (unplugging the mass airflow was just a cheap fix to a different issue that has since been corrected.). My 92 Camry even had an EGR code come up due to a cracked hose, I trimmed the hose down, and it went away on its own. OBD2 is anal and will illunmate whenever it wants.

hoohoohoblin A code tester like a Actron CP9690 works on OBDI Ford, G.M., Chrysler, and 2 Toyota. It does live, graphing, record, smog readiness test, oil light reset, it has code connect for diagnosing codes. It comes in a black pouch with instructions. It works on cars 1983-2013. On OBDI Fords, if you get vacuum at the EGR at idle, replace the charcoal canister purge valve. If you get oxygen sensor running rich, replace the MAP sensor. It could be the CTS or high fuel pressure. The CTS can read low and cause high idle. Electric fans might not come on. The CTS can read high and cause no fast idle and electric fans keep running. The tester can bypass the CTS to check the coolent relay and fans. After each repair, run the engine at 2000 RPM's for 2 minutes and test codes. Otherwise you can get false codes. The tester can erase memory codes. It check ABS.
