Since it has turned colder I have noticed the gas pedal sticking on first starts in the morning. This morning the engine didn't want to start at all. So thinking the throttle plate needed cleaning, I took the intake off and cleaned the plate and area around it with MAF sensor cleaner. Now the throttle seems as smooth as ever. Will know for sure in the morning.

I had the same problem when I bought my Accord (used). You did the same thing I did so it should be good to go now, as it was with my car.

Be glad that you do not have DBW. If you had done what you did to a DBW car, you might be buying yourself a new throttle body. (worse case)

I have a DBW throttle body and I cleaned it by hand using a carb cleaner. Never had an issue.

I agree that a greater care must be taken when dealing with them, but they're nothing special, really.

The Nissans sometimes have issues if you clean the DBW throttle body. You may end up having to do an idle air volume relearn with the CONSULT-III scan tool.

Good tip! I'm sure it'll come handy for me in future. Thank you.

Drive by wire. Most vehicles have gone to it. My 2005 Corolla has it.

I guess both Duratechs have a cable.

Fly by wire is really cool until something goes wrong. Before fly by wire we hardly ever sold a throttle body, since we sell around 1 a week on slow weeks.

It's a great idea/maintenance to clean the throttle body bore and plate.
don't wash it downstream. Use solvent and a rag, screwdriver, fingers. Get it dinner plate clean all around and on both sides.

This fixes all sorts of problems, but if not, it is still a very good start.

I always have washed it downstream. What is the reason for not doing this?

solvents washed downstream (subsequently goes into the combustion chamber) will contribute to lubricating oil dilution.

Q.

Great, so I guess I may just remove it and clean it for my car when the time comes. Didn't think a DBW car would be so sensitive.

Below is the Re-learn procedure for GM cars(figure there has to be one floating around for a Ford).

My 1996 Contour with the Zetec 4 has had since early in it's life a throttle hang up and slower to return to idle speed upon stopping. It's a manual tranny. I looked at the throttle body and it is clean. It's not bad & I can live with it. I was amazed how clean the throttle body is after 15 years. No build up at all. Maybe because I don't use any noticeable oil between OCI's helps. I can go 8,000+ miles between OCI's and not use oil. I've been running Schaeffer's 5W-30 SL Blend with LC 20 & FP 60 since 2004.
