Difference between 1994 and 1995 engines? Swap problems
 

Hello.

About 3 months ago I ordered a replacement engine for my '94 2.2 camry. The parts supplier promised me a '93 engine (completely compatible) with about 30.000 miles on it. Well, once the thing was 90% in, the mechanic discovered that the new engine had largely incompatible wiring, including a different ditributor cap and ignition coil, as well as some emissions components that the original engine did not. Being a clueless !@#$%#$, he assumed that what I'd gotten (I ordered the engine, not the mechanic, or I wouldn't have these problems) was a California-emissions engine.

Eventually he wired the thing all together, but ever since, the car's been eating twice as much gas as it should, and installing a new O2 sensor (this model only has one, not two) didn't make a difference. The fuel-air mixture is far too rich.

To make a long story short, I recently disocvered that the real problem is that 1995 engines were tuned and wired differently to meet more stringent emissions standards in all 50 states, thus the electrical incompatibility. Does anyone know what I would need to do to make this Frankenstein monstrosity work correctly? Would installing a '95 ECU do the trick? Can the '94 ECU just be tricked in order to quit @#@$ing up the fuel mixture?

Thanks for any help.

Somewhat confused. What year of car, what year engine did you have before the replacement (94 or 95) What year of engine was the replacement 93 or 94)

The computer can not be tricked but would think any components needed from the 1995 ? engine could be bolted onto the other engine.

What mileage are you getting now, is the check engine light on?
