I just got done doin a sas on my 88 4runner 22re 5 speed. 2nd drive, Well I went to town, and now it has issues. It will rev ok if u are easy on the throttle, but if u go half or more, it drops rpm, and bogs, dont have a tach but i assume around idle speed. When it bogs it acts like it wants to rev, but it wont. I can hear kinda a whoop sound around afm, like air doin sumthing. I jumped diag plug for codes, and got none. I unplugged my tps, and had exact same symptoms. If i jump e1 and t, idle will drop like it shud. No smoke at all out back, compression is good. I did search, but this perticular problem didnt really come up in searches. I found sum that pointed to TPS, but i unplug mine, and no change in performance, and when I jump the coneectors, idle drops like it shud. Never had a bad tps that wud drop idle when jumped b4. I didnt get to drive it the first drive after sas, as I dont have a license, so I had my buddy drive, but IM 99 percent sure it was running fine at that time, because now it cant go past 55 mph, and on the first drive we got to 70. I know you guys like the tech ˟˟˟˟, but I dont really got none for u right now, if this prob was fixed, i cud post some carnage pics of me mashin on my runner. Help me fix this engine, so I can break the truck

 

I shud add that it fires up perfect, and idles just like a brand new 22re. If u go slow on the throttle, it will rev to around 5k I imagine, but I cant get it to hit the rev limiter, no matter how I play with the throttle. is it possible that when I put the fuel tank in, coud have pinched a line, and that wud not allow enough fuel at WOT to rev, but wud allow it to rev with slow throttle, and idle? That honestly only thing I can think of at this point. The runner never had issues before, was most dependable rig in the world. Now this ˟˟˟˟, and I praying it not nuthing with the injectors, because of it being an 88 and all. Opinions or areas u wud check are wat I am looking for.

 

It sounds like a plugged fuel filter to me, that`s were i would start first.

 

got same answer on pirate, got old one out, goin to get new one in a bit, will post if it fixes

 

changed filter, no change at all, opinions please

 

ok when I did my sas same problem. I'm guessing you dropped the fuel tank for the rear spring hangers? if so check that line mine wasnt even pinched it was just on the wrong side of the bracket which was just enough to starve it when I gave it more then half throttle!

 

Was feelin rear line with pump jumped for leaks, and felt 2 flat spots, and a twist in the line, pretty sure it not supposed to be like that, can anyone confirm, my bud put the tank in for me, aarrrgghhh

 

There shouldn`t be any twists in the fuel lines, or flat spots either that i can think of. Its possible the twist is causing a restriction, but that`s just a guess.

 

yeh i damn positive its the twist, being as how if u rev slow, and allow comp to mix air and fuel it will rev, but if u floor, and demand mass fuel real quick, it bogs, and cant do it. Makes sense to me, I pull tank and replace line tomorrow, and update if it fixes

 

yea thats what happened to me I was gunna cry when it was running like that lol! but was tracing everything then bam the line was just a little tight and pulled it to the other side of the bracket bambo all the power in the freaking world (well all the power a 22re could give

 

Nice out of the blue..."That happened to me..this is the fix"

You get an "excellent"

 

well thanks highlux!

 

Yup, pulled my tank to weld on chev hangers i made, well actually it was my bud, it twisted pretty bad, I gonna replace it, will post if it fixes, which i am sure it will

 

Its FIXED, it was the kinked line where it goes from pump outlet to main line down frame, replaced with one from 86 ex cab, and hello rev limiter!!!!
