Hey everybody my name is Bodie and I’ve been driving rangers since I was 16 my first truck was a rusted out 92 2wd 2.3 kinda butchered that truck and feel pretty bad about beating on it as much as I did but I digress my new project I’m working on I’ve been flying solo for about two years just trying to work out kinks and I’m stumped thus joining trs I have a lot done to the truck so I’ll have to explain further if anybody is willing to help my now truck is a 91 4.0 factory 4x4 I’ve sas’d it and replaced the ecm with a 92 explorer ecm because in all of my 21 years of wisdom I left the battery plugged in with the key on while welding on the truck🤦‍♂️ so what I got going on is I can’t get it to rev above 3000 rpm and I’ve replaced the tps, map, iacv, air intake temp, coolant temp, and checked all of these things prior to replacing most of which were fine just dirty so those went on the shelf. Back to the list I’ve also replaced the fuel filter and tested for pressure all good there as well I’ve supplied pin 30 with 5v from pin 26 and the rear axle I put in it came with a wss not sure on condition but it out of a dodge so I don’t assume it works. Lastly I put the nss on three switches so I can turn it on and off for testing nothing has seemed to work any help is appreciated thank you for reading

So everything was fine. Then you replaced the ECM and now it will not run above 3000? Looks like you need another different type of ECM?
