plumo57

New guy... i have an 86 deluxe with the 22RE... recently installed a rebuilt long block (bought it lacking a number 4 rod bearing... well, actually, i found the bearing in powder form in the bottom of the pan). i added a pacesetter header. the truck is on 31X10.5s with a 2 inch body lift, otherwise stock. Living in upstate NY, i have to downshift EVERY hill i come across, sometimes down to 2nd gear. not a problem in the mud, but on the highway it sure is. I know she's not a V8, but it seems like i should have at least a little more power. any suggestions?

You bought a rebuilt 22re with a lacking rod bearing? Dont get it! I put a new 22re in my truck and it pulls hills just fine with 31's. Its got a r/v cam in it and I have some other stuff on it also! Only thing I would do is regear your truck! 4.88's would do just fine!!

let me clarify. I bought the truck with the number 4 rod bearing lacking. the rebuild i bought later. seems to be fine, except the lack of power. i'm wondering if i should replace sensors, injectors etc. is there a way to check this stuff? thanks

just a 22re

what you should do is get a engbildr rv cam!! i got one and all stock and i can pull hills with 31's and i have 4.10 gears

hard to say what the problem is just by saying 'lack of power'.
I have to downshift my 88 to third to maintain 55 (will actually pull to 65 though but I don't wanna push the rpms) on the 5-6+% grades around me- the grapevine/I-5 and cajon pass/I-15, and it's on 265/75r16 (~30-31) with stock gears, 4"lift and +- 600lbs of tools and gear in the back. my 91 auto bounces back and forth between 2nd/3rd(out of overdrive) to maintain 60 (floored pedal) on the same hills and is on 245/75r15 (~28-29) (iirc).

check your timing, compression, valve adjustments, throttle position sensor adjustment, air filter... lot's of things can affect power output and perceived power output can be affected by when you downshift- wait too long and it feels like you're out of power. you shouldn't be afraid to rev the engine to 5000-5500 'cause it should handle it if the rebuild was done right.

is there a good source for info on doing TPS adjustments and the like, i.e. testing 02 sensors, temp sensors etc? The motor was rebuilt by someone i trust whos done work for me in the past, so i dont think its the problem unless my fuel system is not so hot.

There are two sources I use for the most part to test my vehicles. I have an '86 and a '92 4rnr.

Mostly the '93 FSM because it's so easy to use and covers most everything:

But, more recently and for more '86 specific issues, I use the '85 FSM. It's not as easy to maneuver, though:

You'll need to use the '85 manual for things like your O2 sensor and auxiliary air valve, but the '93 should cover most everything else.

You'll need Adobe to read them.
