on my screwy "engine temps"
also some other problems
i had used an infared temp. scanner to read the approximate engine temperatures, and it was nowhere near the 280 the gauge said. well today i got a scanner on it, and found out a few things. First off, the gauge is wrong as i suspected.
what seems to be happening, is that the gauge IS reading in parallel with the real temps, but just way high. but only to a certain point.. then when it redlines, it may immediately fall back down to normal, or it may stay spiked for a while. either way, i verified that the sensor is good and the computer is reading it correctly, and that the gauge is just bad.
So, now i have a couple options. i can replace the dash cluster. is this a lot of work?
or, i can run an aftermarket sensor up onto the dash somewhere (does anyone even make these?)
Also, i had no KR when i floored it in second, but i still need to do a full run.
this is an OBD-I car, and i could not read timing. is this possible? it worked fine on the OBD-II impala. there are a lot of things i don't know how to use
there is a block learn, which was a 147. the way i read it is that if the number is over 128, fuel is being added to the engine to compensate for a lean condition. if below 128, fuel is being taken away to compensate for a rich condition. THEN, there was another "rich/lean" flag, and this said that the engine was running rich. why is it adding fuel, compensating for a lean condition if the engine is rich?
also, the A/C clutch is always disengaged, even when i turn AC on. the AC has always blown, but never been cold. i assumed it needed a recharge, but didn't care.. (MN weather
) and the fans do not engage even when i turn the AC on. could these 2 issues be related?
