Hi, yes this is my first post. I recently purchashed a 92 5sp SHO from the origial lady owner in great condition for $2000. I currently has 160K original miles and I have receipts for the 60K and 120K service. It has had synthetic oil changed every 3000mi since new. Mechanically it is in great condition.
Now, when I bought the car about a week ago sometimes it would run OK, sometimes it would barely run, stalling and quitting for no reason. I checked the trouble codes, something about MAF sensor out of range and the 10deg timing default. So I replaced the MAF sensor and the cam position sensor and reset the ECM and it does better. But starting off is difficult because when you push the gas (in neutral or in gear), the RPMs drop about 200RPM before they pick back up. It is sluggish overall and it still dies sometimes while idling, even in neutral. I haven't driven the car except once or twice because I am nervous about it.
Anyways, I checked codes again after replacing those, it still says timing default to 10deg and now it says TPS voltage lower than expected. So I reckon I will get a new throttle position sensor today also.
I was futzing around earlier today and I discovered that the passenger firewall side SPOUT jumper is missing (I didnt knwo what it was, I looked it up). Now if this is simply a jumper, could I just cut the connector out of the circuit and wire it up with some generic electrical blade type connectors? If not, where would you go to get another jumper?
Also, I was looking around and found these two items below the coilpack area:
I have no idea where the first one goes, but the second one looks like an IAT, or some similar air temp sensor, does anyone know where that would go? I know these two items could affect the engine controls significantly. Thank you for reading this far.
