Hey so im new to this forum. I have a 2wd 1997 Ranger with the 4.0L with about 255xxx km on it. This problem began when i was driving around town and found that when i stopped my truck would sometimes stall. It would start back up and be fine, i just found it a pain to drive. This persisted for about a month or two and i didnt drive it much during this time. Then until recently it stalled while i was driving so i pulled over to the shoulder. It wouldnt start back up and i had to tow it home. I have replaced the fuel filter, put in fuel cleaner, replaced canister purge because i was reading code anyways, new air filter. The pump seems fine and the check engine was on prior but has been of since i disconnected the battery. It turns over but then has high or low idle and sputters to stay alive, if i give it gas it helps but it dies eventually anyways. Ive seen similar forums that suggest IAC, MAF, vac lines, etc... any idea if this can be narrowed down so i dont throw a lot of money at it only to have no results. Thanks, any help is appreciated.

 

It would be helpful if you have any codes that were present. Recommend re-scanning for set codes and going from there.

 

I'm having the same problem I can't figure it out either. I changed oil an filter, changed pcv, injector cleaner, an cleaned the iac an maf, nothing has helped, the truck is running like shut it stalls an bucks an idles weird

 

driving around with a nearly plugged up fuel filter will over time will damage the fuel pump

2nd / when the engine is warmed up , pull EGR vacuum hose , and listen for any engine rpm changes

smooth idle / erratic idle
