Bye-Bye codes! I routed some new vacuum lines and got a 111 on the KOER test. I still get a 511 on the KOEO test, but I seem to remember that the chip throws that code. Anyway, I took the l'il pony out for a spin and she's runnin' great! It was kinda doggy when the check engine light was coming on. Now its back to pullin' revs & plantin' my weary arse firmly in the seat. It seems to run cooler too. I don't really drive it very often now that I have the '06, but over the summer I took the '94 out one day (check engine light came on) and I noticed that my water temp was really climbing. I shut the A/C off and it was still running hotter than usual. I started getting concerned that maybe I had blown a head gasket. After that I kept a watchful eye on my coolant level and never noticed a dramatic loss of coolant so I figured it had to be something else causing the high water temps, but I wasn't sure what the culprit was. Anyhow, it appears that all is well now and I'll be able to take it over to inspection so I want to thank you guys for providing me with the insight for getting a handle on those codes.
