1994 Honda accord EX, Auto Trans

Bought the car, motor was blown.


Got SOHC VTEC from a 2000 Accord, put it in. Used 94 wiring harness, and 94 distributor. Ran fine for about a week, then stalled and wouldnt stay running.

Got it towed to the house. Checked it out. Had 2 engine codes. TPS sensor, and Fuel Injectors. Fuel injectors was the main fuel relay. I replaced it.

Installed new TPS sensor. Set reference voltage with key on. Closed throttle was .5 volts, Wide open throttle was set at 4.5V. Volts, not Ohms, mind you, by reccomendation of the TPS thread on the forum.

Now, here are the problems occuring now....

Car starts fine, idles fine, but when you put it in drive it hesitates and bucks for about 20 seconds, then it will go fine for a while, then start running like crap again.

Also, if you turn on the AC, you can't get the RMP's to go up, the car bogs down and wont go above about 750-800 idle rpm. You cannot drive the car or attempt to move it with the AC on.

I have no ECU codes now, but it still wont drive. I don't know what else to do.

I have also put in new fuel pump, and fuel filter.

Maybe the ECU is bad? Or I didn't set the TPS sensor properly?

I need to get the car on the road, gas prices are killing me!

Thanks for your help guys!

 

What injectors did you use?(94-peak and hold injectors-resistor required) (2000-saturated-no resistor required) If you used the 94 harness and 2000 injectors, you may need to jump the resistor box to give the 2000 "saturated injectors" a full 12 volts. Or you can use the 94 injectors.

 

It was running just fine. I dont see how the injectors could be the problem now, but maybe they are.

I think I used the 2000 injectors. Where is the injector resistor box anyways?

Also, would adjusting the idle screw in the Throttle Body, without unplugging the MAP sensor have anything to do with whats going on? I read on here that you have to unplug the MAP sensor when adjusting the idle screw on the TB. Maybe the ECU cant get a good reference point?

 

No check engine light on right now, but when I check the jumper wire, it comes up with injector code.


I'm thinking I used the 2000 injectors, hence why all the sputtering and hesitation.

Can someone confirm that using the 2000 injectors would cause these problems?
