Il state the problem first so if you dont know. you dont have to read the whole thing.
1989 Toyota Supra 7MGTE, 5 Speed.
PROBLEM. Car will not accelerate more than a half throttle, starts to try and die but never turns off. Sometimes back fires like to much gas.
Problem starts when it tries basically to go past 2500 to 3000 rpm. But also feels like it not getting enough gas like its being starved.
On first start up you can do 2 or three pulls before the above starts to happen. Once problem has started you can turn the car off wait a few seconds and do another 2 or 3 pulls.
But just barely giving it gas just enough to get down the road pretty much hinders it from cutting out.
Attempts to fix, No check engine light, but pulled codes anyway and got a code for TPS. Other than that no codes, and no codes will Attempting to fic
1. Installed new fuel Pump
2. New fuel filter
3. New TPS, did not calibrate cause no OHM meter, but marked it the best i could and installed, No longer threw a code.
4. New Spark Plugs, all gaped to factory.
5. AFM cleaned out. Unplugged the AFM to see if the probelm was the same but without it plugged in it would just die the moment you hit the throttle. so ruled that out.
6. Fuel Pump relay mod, bypassed the relay just to see if it was cause it and problem still perused
7. Fuel tank was real dirty(also fuel pump filter looked really bad) so cleaned it out the best i could, problem was still there.
Bought the car 8 hours away, test Drove it and drove fine. Drove the car back, and the first 4 hours back was in Pouring down rain. Once the rain stopped stopped and got gas and for the next 4 hours was the worst drive ever.
Kept cutting out like i stated above, the more gas you give the faster the RPM drop. barley giving it gas keeps it running but wont cut out. enough time basically to pull over lol.
Thanks in advance, about to give up.
