Hello,
I have a 98 ranger 3.0. Two weeks ago I was getting a code for bank 1 lean. I replaced the air duct because it had a large tear and was held together with tape. I cleared the code and the code hasn't come back.
After driving it for two weeks without issue I tried turning it on yesterday. The engine would turn over but stall after a few seconds with no check engine light. I got it towed home and today I have been troubleshooting with the air intake.
I removed the air duct from the throttle body and the engine was at least able to stay running with a horrid misfire. When I tried to open the throttle it would stall. A code for air intake temperature came on but that is because I disconnected the sensor to remove the air duct. I then removed the idle air control valve and plugged up the air passage to the intake manifold with a rag. I started it again and it started out rough but once I opened up the throttle the misfire went away and I was able to increase and decrease rpms without issue. I thought I had it figured at that point (bad IACV), but when I turned it on later under the same conditions the bad misfire wouldn't go away and would stall when I opened the throttle.
Am I going down the wrong road looking at the air intake? I doubt that its a fuel/electrical issue but I'm not sure what more to explore on the air side. Other than a sensor that I'm not aware of.
If anyone has experience with this issue I would greatly appreciate the input.
