I swaped 7AFE in my 94 celica ST. Now the only way to start is to spray some throttle body cleaner in intake and it starts right up. I changed the fuel filter, verified there is spark when cranking and fuel injectors fire. Changed out the temperature sensor. Double checked all wiring and vacuume lines.
One thing is noticed is once the engine is running, the rpm will flicker if I turn the headlights on. Also If I put the car in drive, it shuts down. It will run in reverse though. Any idea? thanks. |

I have disconnected the battery a few times so I would think it would reset the ECU. Yes this engine was out of a 93 corolla. The only two sensors I know of in the intake is the TPS and IACV sensor. I can swap those out. I double checked for ground problem. When the car is running, the battery terminals show 14 volts and there is less than .02 voltage between engine block and negative battery terminal so seems like engine is grounded fine.
Well I observed the behavior again today. As soon as I hit the over drive button, the car starts to bog down and the the temperature gauge goes all the way to max. So some kind of electical issue there. Also when I put the car in drive, and hit gas the speed goes up but the transmission does not shift. Essentially it stays in 1st gear (I dont have the wheels on and the car is on jack). |
