I've done a bunch of work to the truck and its still running like crap.

I was poking around on the AutoZone website and noticed the 2.5 calls for a different plug then the 2.3.
The only real difference is the stroke of the engine(different crank), I'm still using the 2.3 ECU and accessories, but could the plugs really make that big of a difference?

I'm running Autolite iridium plugs, the part number the 2.3 calls for, not the 2.5.
Again, I'm using the 2.3 ECU and accessories, with the 2.5 longblock.


Edit: I haven't been getting any codes except the nagging 1443 code, I also replaced all of the ground wires including the main ground that goes to the engine.

I just looked again and now its saying the 99 2.5L engine uses the same plugs.

I guess its going to the stealership to get fixed.

If it makes you feel better my Explorer has had a lean engine code for like the past 2 years that I haven't been able to figure out and it hasn't melted down yet.

Mine started making a rattling sound from the exhaust around 2500/3000 rpms.
I'm not sure if its coming from the converter or the flange on the header, the studs were really rusty when I replaced the gasket so they might have come loose, but I don't hear an exhaust leak so who knows.

I'm not sure if it has anything to do with how my truck has been drinking gas, but it threw the code P0340 (Camshaft Position Sensor Circuit Malfunction).

This is the first time this code has come up.

I'm going to replace the sensor tomorrow and pray thats whats been causing the problems.

"The camshaft position sensor identifies position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown"

Hrm, my oil smells like gas, I get bad fuel mileage and my truck has a random misfire and lack of power at times.

I just LOVE spending all of my money on my truck.
At the same time, I'm glad it threw the code, now I don't have to take it to the dealership like I was planning.

My "master ase certified" father couldn't figure this out, just goes to show that a piece of paper doesn't mean you know what you're doing.
