We have a 1989 Toyota 4runner with a 22RE Fuel injected.. It's got a miss in it when you accelerate. The truck dies when you put it in gear. I checked the codes and it's throwing a 52 and a 21. I looked up the 21 and it says oxygen sensor which would come up anyways because the sensor is unplugged. I can't find 52 anywheres. Can anyone help me out??

51 is knock sensor.

double check your timing is at 5 BTDC, reset the ECU by unplugging the fuse in the kick panel (or disconnecting the battery) for 1 minute, then see how it goes.

just a 22re

Most likely its the TPS (Throttle Position Sensor) It will make your engine do some crazy stuff. Misfire, ilde ruff and die.I have ran into this a lot on different trucks that i've worked on,try that first and see what happens.If thats not it let me know and ill think on it somemore. The TSP is on the front left side of the air intake across from you throttle cable, between the valve cover and the air intake above the water neck. In case you didn't know

I hate to correct abe, but the fuse to reset the ecu is in the fuse block next to the battery on an 89. I think we had that trouble with my truck abe.

lol. .thanks.. that i didn't know but my boyfriend would.. he is a mechanic.. i'm not working on this alone haha that would be dangerous.. we did just change the fuel pump and it works a little better but it only worked a minute before it shut off.. thinks we blew a fuse

Let me guess...the 15 amp EFI fuse???

abecedarian

oops. my bad.
by all means correct me if I'm wrong.

MudChick62

Not sure what fuse.. It was a 30 amp something lol.. But the gas tank caught on fire so we kinda have to fix that before we can fix the fuel pump .. Pretty sure that's what was wrong. It was running a lot better.

91Toyota

lol...yeah you definitely need to fix that. Good luck! Just buy a fuel cell and mount it in the bed

bigt

yeah im going fuel cell when my gas tank gets a rock into it!!!

91Toyota

Very nice. I'm just a poor kid who drives the crap out of his truck...so a fuel cell isn't necessary for me...unless I do a 7mgte swap

abecedarian

sounds like 2 good reasons to have a cell

bigt

well i figure if i upgrade the trail rig i have lots of spare parts for the dd

that and i kinda like being broke

91Toyota

lol...I got a cell...phone

LOL...that works kind of well. My parents would kill me if I had spare parts laying around. I can hardly have an engine in my garage. Then they start b1tching about it...lol

bigt

yeah im actually building a 4runner car port work pad besides my garage
once i finish buttong up both 4runners .. where i can have axles and parts or do a s.a.s or buy old yota and fix it...i have had some major oil spills and i have to reseal the whole driveway then only work on my pad but its worth it and you gotta learn some how

91Toyota

LOL...yeah. I don't work on any of my vehicles in a garage. When I took my truck apart it was snowing...lol. I got a dining canopy out and put it over me...but I still got soaked!

Yeah, you definitely got to learn somehow...and I like experience

Sounds pretty cool though!

MudChick62

We fixed the fuel pump.. They epoxy-ed up the top so the wires don't short out and cause another fire lol.. The truck is out there running now and it sounds better than it did before we put the new (used) pump in. Maybe we found it?? I guess we'll have to wait and see..

MudChick62

The truck works fine : ).. it was the fuel pump .. thanks for the help though : )
