1999 s-10 2.2l rough idle with following codes
Hi all,
Son just bought his first truck. 1999 s-10 Extreme with a 2.2l and 200K miles. Started it up, smooth as silk. Drove home 3 hours with no issues at all. Parked in yard for an hour then drove about 1 mile before it lost power and ran rough. Drove it home, left it an hour, started up no problem. Drove 3 miles, same problem. Did it again a few more times... Bought a code reader and got the following...
P0300 -multiple engine misfire
P0113 - IAT sensor circuit high intput
P0122 - TP sensor circuit low input
Any ideas?
Thanks

Welcome to the forum. P0113 and P0122 sound like a wiring problem. They should be wired as follows.
IAT:
Terminal A TAN wire, IAT Sens Sig, to PCM connector C2, terminal 20
Terminal B GRY wire, IAT Sens +5V, from PCM connector C2, terminal 28
TPS:
Terminal A GRY wire, TP Sens +5V, from PCM connector C2, terminal 33
Terminal B BLK wire, ground, from PCM connector C1, terminal 57
Terminal C DK BLU wire, TP Sens Sig, to PCM connector C1, terminal 21
