    2.5L ('98-'01) High Idle

    I've been having high idle issues for a while now. When the engine is fully warmed it will idle around 1100-1200 RPM. When shifting gears the rpm's don't drop. They only drop (very slowly) after I come to a complete stop. The engine seems to run better with the IAC Valve unplugged, around 750...
  3. Ranger Problems....

    2.5L ('98-'01) Stuck engine RPMs until dead stop - gone fishing

    The truck is a '98 XLT with the 2.5l 4cyl, manual. When driving (hot or cold, highway or in town, 25ft or 200 miles) the engine speed stays high, or goes higher, when depressing the clutch. It will stay there, no matter what, never come down, until the truck comes to a dead stop. I've coasted...

  7. The Dreaded Lean Code

    Hi everyone! New member, have been stalking the forums for a while now, and I finally got my hands on a ranger. Oldie, but seems in fair shape. Only issue I’ve found so far, code P0174. Pops up fairly often. Not every time but often. Truck doesn’t idle super smoothly, but it isn’t terrible...

  12. High Idle / Emissions Problem

    I have a 98 ranger, 2wd, v6 3 ltr, Vin -U. I've replaced the thermostat, egr, ecg, 2 o2 censers and some fuses. The only check engine code coming up is P0401. My exhaust does smell rotten but I have several catalytic converters. The code doesn't narrow it down for me. Is there any other, less...

    I have a 1991 Ranger 2wd 3.0L manual that has a high idle problem. When you first start it up, it revs high for a minute like it normally would when it's cold and then drops to normal or close to it. When you start driving and push in the clutch to shift, the throttle seems to stick at...
  15. Bouncing / High Idle problem - 1999 Ranger 4.0 4x4 Auto

    My truck idles around 1,000 RPMs (after warming up) and seems to like to jump up and down. It will jump up to about 1500 RPM for a few seconds and then slowly drop back down to 1,000 RPM. I thought it was my AC causing the idle to increase and decrease so I unplugged it to check and it didn't...
