22re starts ok when cold. stumbles and dies after 2min
Hi all, new member here hoping to get some help with my 93 22re pickup w/400k mi. It will start OK when cold, but when idle drops after a minute or so, it will start misfiring,shaking, then eventually die. If I unplug o2 sensor, it will stay running, but with very rough idle. I checked for vacuum leaks visually and with starting fluid. Same result. Would a bad fuel pump or dirty filter allow it to run for this long at high idle?.

PS: I forgot to mention, the only sensor that showed a really weird reading was the coolant temp sensor. It showed infinite resistance when cold(40 degrees), but after engine warmed up for a bit, it showed about 50k ohms. Could this sensor being bad cause the truck to be undrivable? Thanks in advance for any input you guys may have.

Hello brian.
just recently there have been a few very similar, if not exact, problems being posted about and discussed. please go to google and typ ein "yotatech (insert search words here)" and you will find lots of information. if that fails, im sure people won't mind posting then.

Going to pick up a new temp sensor tomorrow and see if that helps. I found other similar threads, but not too many that sounded like the exact symptoms I am experiencing.

A fluke multimeter. Put in new temp sensor, same problem. I did find a few mouse chews on my o2 sensor wires, so I ordered a new o2 sensor as well since this one has about 200k on it. Couldn't find any other apparent damage to any other wiring. Tps and AFM check out OK. Removed and cleaned the throttle body as well.
