No progress, in fact, its gotten a bit worse. LTFT was sitting at -14 at the light the other day. I am more curious about the motorwest injectors than anything. When work slows down I will pull the rail off and put the oem ones back in. My fuel economy has gone to crap. Im lucky to get 200 miles...

Can you post a pic of your data graph? I think I mentioned that I threw a p0420 code a couple of weeks ago. Cleared it and it came back. I have a suspicion of exhaust leak pre 02. It sounds like we are having similar problems. Both 98’ runners, im at 314k, similar components. Cat should in...

Hmm I might give motorwest a call today, ill let yall know… timmy the tool man gave them high praise and he usually doesnt lead one astray -98Gate

I am pretty sure I have a small exhaust leak too, either at the headers or crossover pipe. It definitely could be throwing off the O2 sensor but -11 is pretty dang rich. Mine is running rich as can be at idle and deaccelerating and braking. Under a load trims are great. I might take one for the...

Update New FPR is in…. and while I definitely had a fake one installed before, the new one isnt performing much better. Data showing still around -11 LTFT, I will put a picture of the data from my drive today. I am just stumped and tired of firing the parts cannon. Calling on all of the gurus...

Oh you bet I learned my lesson on that. The old “don’t fix what ain’t broke”. I hate to admit it, but on my old 4runner, I give it the best I can put into it(except ebay china crap apparently lol). I took my dang drivers test in this thing. Been through many girlfriends riding up front and many...

I agree… that partsouq one looks legit. Might just go with that one. I appreciate the insight. Something about the denso logo just looked….. off. Welp get to have another fun go at getting the manifold off. Ill let yall know if that fixes it -98Gate

It definitely did NOT come in that kind of box. It came in a red and white “paper” box. Not that thicker cardboard. I still have the box it came in. What is the consensus here? Assuming this is a chinese part, could that be enough to jack up my fuel trims? I am not sure just how sensitive or...

Compare the font to this one…. Can anyone take a pic of one off of their truck to see if I am crazy?

I apologize, it runs into a hardline under the manifold then to the intake tube. Does this look like an OEM denso? Something about the font looks off… maybe im running a shanghai special…..

I replaced it just to sort of cover the difficulty of replacing. It was right there I was doing the intake plenum gasket reseals to stop coolant leak. Figured id do some preventative maintenance so to speak. Could I disconnect vaccum line from the manifold and see if fuel is leaking past it...

Just starting off at the LTFT issue, and worrying about the random stall later, where would you start? I cannot figure out the proper way to troubleshoot this if I am sort of chasing a ghost. Other than letting it get bad enough to pop a code. -98Gate

Yes they are Motorwest stock replacements -Plugs- Denso IK16TT(rock auto) Wires- DENSO 6716182(rock auto) Coils- DENSO 6731201 (rock auto) Crank position sensor- DENSO 1961109(rock auto) Camshaft positon sensor- Toyota 19300-62010(ordered off amazon came straight from japan) Fuel pressure...

I would assume cleaning the IAC and be sure to order a gasket from rockauto(along with any other random stuff you need to make the shipping have some bang for your buck). Maybe a set of brake pads or something you know you’ll need in the future? Getchu a toothbrush, throttle body spray and get...

Gosh, something in the water right now. I am having the exact same issues as you. Have the motorwest injectors as well. No code, no misfires but terrible fuel trims. The last thing on the list is the fuel pump….. i I dont see how the pump could make the truck run rich though. Fuel pressure...
