Thank you both for your insight, things to consider in my quest. I think the mis-fire and the low power are two separate problems. In reading through more posts yesterday, I ran across one that had a heat related power problem, similar to my lack of power, and a couple of the suggestions to him were to check the fuel pressure. And that brought back to mind that I had to replace my fuel regulator at the intake rail, due to a huge fuel leak when ignition was on. I found a used part on Ebay and fixed the leak, but now I have ordered a new replacement to eliminate the possibility of the used part being defective. Since I will have to remove the intake plenum (once again) I can check the resistance of each injector then too. Still can't find the mis-fire though. Like I said, Pulling the plug wire on #4 doesn't change the miss, but neither does pulling #5 wire. I'll ask around for a shop that could do a diagnostic to determine the firing/mis-firing. Any other thoughts? DD

This will be my third and final attempt to post this. I just replaced the engine in my 90 Warrior V-6 AT with a long block from Champion engines. I finally got it running after multiple setbacks, fuel, coolant and AT fluid leaks. And it only runs on 5 cyls. I can't determine which one the miss is in pulling the plug wires individually at the cap while running, #4 does not change the miss or idle speed, but neither does #5 wire either. The compression is good enough, 150 lbs in all but # 4 which is 140. I took it to my local mechanic and he could not get the timing right, so he suspected that the timing was off a tooth on one of the cam sprockets (most likely drivers side) I pulled the upper cover again to check and the marks were all perfect still. I took the valve cover off on drivers side to check valve clearances and they were all within limits (some too loose, none exceptionally tight.) During the rebuild I replaced the distributor with an aftermarket, the injectors with 4 hole aftermarket, plugs and wires and of course timing belt and all the components. The engine starts fine and idles smoothly except the consistent miss, but has no power at all, could not climb any grade of a hill and only revs to 2500 in gear. I don't know how to determine if the injectors are all functioning, can't imagine getting a stethoscope in there to hear them. I wondered if the replacement distributor could be the culprit also. I ascertained that the timing mark on the balancer when at 0 , the #1 piston is at TDC, so the shaft key must be in place. I am flummoxed and would appreciate any suggestions / ideas from all you seasoned wrenchers. Thanks in advance Desperate Dan

I have read a good many of the great ideas for engine swaps, and appreciate the details that I got. But I didn't see anyone mention of using the 4 liter engine from the '90 Toyota Land Rover. I'm wondering if that block could fit my Warrior too?

Hello, we're new to forum and new to Toyota MH. We lost our spare wheel/tire on the road (bounced off chain bracket). Need help in locating a good used one, 6 lug/14 inch. We're in Fla. panhandle this week and heading back to Maine next week. Also need help locating source for a pair of small airbags for our Mothership. (She's sagging). Appreciate any help.
