Power loss/surges??
 

Hey folks, got a manual 1998 Ranger 3.0 4x4. Been having problems accelerating, especially from a dead stop. It would speed up fine, but all of a sudden slow down then pick back up again.. At first it would just be the first couple gears, but after riding on it for a month now, it seems to happen almost every time I accelerate no matter how fast I'm going or what gear I'm in. And just recently I had gotten a check engine light.

I'm not gunning it, and I can usually ease into the clutch slow enough so it wouldn't happen, but is gradually getting worse. Any suggestions? Any would be helpful, thank you!

sounds to me like a misfire under load...what is the code that its throwing...ever due a tune up on it

Tune up was supposedly done before I got the truck (guess it won't hurt to try), but the code that I got done yesterday read PO306...but also had Catalyst Monitor, EVAP Monitor, O2 Sensor Monitor and O2 Sensor Heater Monitor - all of which hadn't completed self-testing.

id check the converter it might be clogged...my buddies bronco did the same thing when his cat was clogged

I've had people tell me the same thing, think I'll give it a go. Thanks man!

no problem
