new injectors rotor and cap, fuel filter perfect timing wtf??

[speak]

i have been reading posts and changing a lot of parts. still pulls out like a model t ford, but then rev's out hi end. i installed new injectors, new vac. lines, fuel filter, and new plugs wires cap and rotor. new alt last year. took off valve cover and no valves were hanging up. timing is perfect only 1900 miles on new 22re. truck was running fine. i was driving on a light trail ride, and let the engine bogg down in 3rd and almost stalled out down shifted and just like that it felt like something got clogged. also i checked fuese and also unbolted the cat to see if it was clogged. still nothing. this is my daily driver and plan to keep it that way. please help

Could be a bad coil.

replaced the coil. still same thing. sometimes its rough to start but it idels rough. still no power feels like it cleans out around 3500rpms but even then it still does not feel like it wood when it was running right.

wrong firing order? some firing orders can be close and run like crap at first then seem like they clean out, or vis-a-versa, it'll idle good but wont rev up nicely.

Test your AFM and TPS. There's writeups on 4crawler.com

the firing order was right. but i unplugged the tps while the engine was running and nothing happened. does that sound right? i wanna check with a voltage meter to see if its even working. jus waiting on a voltage meter.

could my distributor have skipped a little or be bad?

I just found out how to check the codes. it was a code 11 so yea the tps is messed up. im gonna check the resistance of it replace it if its broke. hopefully that will solve my problem.

I changed the tps no difference. It's a code 11 how do I check the ecu?

Download the FSM in the sticky on the top of the page. There's a portion of the EFI section where it tells you how to check your ECU, rule out your wiring harness, ect...

The good thing - you're going to have all new parts on your entire truck by the time you're through. :toilet3: :rtfm:
