Put a 95 engine in a 2000 TJ
I blew my original engine (4 cyl) in my TJ. I found a really cheap one out of a wrecked 95 with low miles. I was able to start the 95 before I took it out and it ran fine, it was rear ended by a semi. I swapped them out, which went pretty smooth as far a engine swaps go. My problem now is I have a slight hesitation, almost like it's missing or even bad gas ( but now have ran 2 tanks from different gas stations through it). It does idle just a little rough and I kept the 2000 wiring harness. Here's what's new. Plug wires, coil (2000 - could that be the problem??), plugs, Serpentine Belt, Distributor cap, rotor, Throttle Position sensor, Crankshaft Sensor. All new parts were bought for the 95 engine except the coil. I have checked all vacuum lines and grounds, all seem good.
Any Idea's on what would cause the hesitation? It's not throwing any codes now. It was giving me a P0201, but I changed the injector and that went away. It seems worse in 2nd and 3rd gear.
