I did a bunch of mantinance on the 94 sc auto I just got. I did plugs, wires, fuel filter, 02 sensors, belts, oil & filter and cooling system flush and 180 thermostat.
The car didn't have a thermostat, and would run hot, previous owner has adapted the wiring with a toggle switch to run fan constantly if you want. I noticed it has started to melt one of the fuse's in the underhood box, and want to remove all the wiring and put it back to stock. The factory gauge shows it running at around the M to about 3/4 up the gauge still while driving in traffic but once I am cruising at a consistent speed it runs a bit cooler. Fan is coming on and going off at 220 and 210. I have used my infrared thermometer to check this. Fan on is 220 which reads 3/4-7/8 up the gauge normal range and fan off is at the right of the M.
I did alot of reading on here that with a lower temp thermostat it's a good idea to do the calibration to turn the fans on and off at a lower temp. Anyone here in socal do this? How do you do it exactly?
The cooling system didn't look rusty or clogged, but all it had was plain water in it. So hoping that this will resolve the cooling bugs. I'd really like to be able to enjoy the car with out worrying about overheating.
My other questions, car would missfire under heavy throttle, make great boost but felt like there was no acceleration. Was getting codes 181, 185 and 189 If I recall. One was a mass air, the other two were 02 sensors showing max addaptive limits for a lean condition.
After doing plugs and wires, it feels much stronger, although it feels sluggish from a stop until boost comes on. I've not had a sc before so not sure how the car should feel ideally. It pulls strongly but I hear knocking at heavy throttle after 5k rpms. Plugs are gaped at .050.
Rechecked codes now I only get one about 02 sensor not detected on bank 1, lean condition assumed? I can't remember the number.
Any advice on this? wiring for 02's looked good.
Thanks!
