RPM pausing @1000rpm's when down shifting...

[Fried One]

GhettoPop,
Thanks for posting, I cleaned the cylindrical sensor today. Used Motomaster throttle body cleaner. It was not gummed up or that dirty. Also checked my pvc valve while i was at it. It too was moving freely. Had a bit of oil on it though. Is that normal? Could I use WD40 to clean out the MAF. I am not sure how but I will check it out.
I hope I don't have to set my TPS. This is my second TPS sensor.I have not loosened the screws since. My rpm seems to idle steady but only sticks on the drop. So I am thinking it might not be my TPS. What is the round thingy with round holes around the chamber..situated at the throttle body on the back between the TB and firewall. Could that sensor not need cleaning as well. I know there is a spring loaded chamber in there. I will also clean out the TB as you suggested. I know it is a bit dirty as I took a rag and just wiped some of the carbon in there. I was always skeptical to use any throttle body cleaner due to the coating.

NO WD-40! as stated above elec contact cleaner or something similiar!

I believe oil on the pcv valve. as long as you hear a clicking when u shake it, its good to go. The round thigy i believe is your EGR valve which i doubt is your problem.

trust me, soak a rag in TB cleaner and clean the crap out of the TB. then run engine and spray into TB as per directions on can. u'd be surprized how dirty it is and cleaning will make a world of difference in throttle response, and sometimes idle. i clean mine every 5k miles, as a matter of fast, i'll be cleaning it today!

i really think your TPS is the problem, its not hard to adjust man.

Just my 2 cents... but you might want to go ahead and replace the TPS (throttle position sensor) as well if you haven't already. It's only $20. Set the voltage at .99 and that might do it if nothing else does. When mine went out it revved until it died, but who knows.
