. The only thing that I see that could have any effect on that should be the vent pipe. I'm not seeing any kinks, flat spots or damage from the outside. I'll have to check that it's clear inside the line but It looked like it's going to be a task getting the fill tube cover off located inside...

I have a 98 4Runner SR5 5VZFE 2WD that's been sitting out of commission for a few years. I now have it all back together, running like new but have an issue at the gas pump. If I try to pump gas regularly, gas starts back flowing out the fill tube. I have to barely squeeze the handle, edge it...

I'm going to give this a go when I get back to it, since it's past due anyway. I've been told that wouldn't cause it by more than one person but also the one thing I haven't tried. I'm not coming across any record of testing the O2 sensor and don't recall if I did either. Now, being able to get...

It's a 98. I did a smoke test yesterday and I have smoke coming from the iac valve and slightly out of the PCv grommet. It's not coming from where the iac valve meets the throttle body but from where the plastic piece with the plug meets the body of the iac valve. Not sure if it's related but...

Finally being able to get the fuel trims makes it obvious what I originally posted is not the issue. If it's been over compensating the fuel,I now know how the plugs got to looking that way. I'm mostly certain it's not the MAF due to having tried multiple, new and off of a working vehicle. Even...

I was able to get it into closed loop and get the fuel trims. I attached screen shots of the various readings I was getting. The CEL was flashing because of the misfires and once it stayed illuminated the fuel system would stay in open loop.

It's been a couple years since I popped the hood on this project. I know I replaced the plugs at the beginning but pulling them today, they look pretty bad and even though they're said to work, I can't figure out for the life of me why I would've gotten platinum. I usually stick to oem with all...

Tested everything as you suggested. Yes there's 12V at every injector on the B-R wire and I believe I just figured out why I wasn't getting 12V at the ECM. I went off of the original picture I posted to determine which pins but just realized there are more plugs in the picture than there are on...

Misfire is nasty enough that it kills when put into gear. I do get a flashing cel... Yeah, I know better than to skimp on parts. I am mostly confident it's not a parts issue. I've had the vehicle for almost 20 years, doing all the maintenance and mechanical work myself so I've learned the...

Fuel trims aren't registering because It's not going into closed loop. The temp is registering on the OBD scanner.

Nothing changes when moving the coil. The spark plug wires are in the right order, verified many times. I did replace all the injector pig tails due to them being brittle, soldered and heat shrinked.

A couple years ago, I burnt a valve so I had the heads reworked and replaced, along with the timing belt. The misfire started after this. I've had all the work double checked by a buddy who is a full time mechanic and everything checked out according to him. Took the intake off, used gasgacinch...

I performed the test with the key on, engine off. 500-700mv on all pins besides 1 which was only a little over 5v. I used a good battery, fully charged. Do you have any suggestions on what my next step should be?

98 4Runner 3.4L I do have an OBD2 reader but here is the issue. My Fuelsys stays on OL and doesn't go into CL as it should once the engine temp reaches the temp that it should switch so my fuel trim stays blank. I'm thinking this has something to do with whatever is causing my misfire. It...

I'm dealing with a random misfire that I've exhausted every option that I could think of and followed the tech service manual flow chart. There is one part in the diagnostics of the service manual that doesn't seem to be lining up and was hoping I could get some input. I'm checking the voltage...
