Difference between 1994 and 1995 engines? Swap problems

[feanor70115]

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.

why don't you try switching the ecu with a 1995 one from a salvage yard wouldnt hurt trying

This is a bit confusing since I thought 96 5sfe were changed because of the OBD-2 on the gen 3's not the 95 ones. Since I have the 95 5sfe and it's OBD-1 and it only has one cat. Unless there was an in between change that involved 94-95 and 96 being completely different.

1995 CA emissions standard car has 2 cats, 1 on exhaust manifold, the other on the exhaust pipe. The differance between 94-95 engine years should be minimal, perhaps a change in distributor which could be swapped out with the one from the old engine.
