Car idles while driving

[playoun]

Hello all,

I have a brain scratcher for you!

I have a 2001 Nissan Sentra, auto transmission.

On occasion (more and more frequent) nothing happens when I press on the gas pedal while driving (RPM doesn’t increase, it actually starts going down when this occurs). Usually happens in 3rd gear (I think always), lasts a couple of seconds, pressing on the gas pedal a couple of times and things are back to normal; acceleration is very slow after this occurs.

I thought it was the gas pump, changed that, no go.
Took it to the dealer, they said it was the ECU...bought 2 used ones with the exact PART# (23710-5M105) so I know they were the good ones...no go.

I have 2 errors; P1130 and P1165 both are related to the swirl control valve.

What should I do, replace my MAF? Are there sensor I can change, if so which ones and where? Should I be looking for some bad wires or clogged valve of some sort, maybe disconnected or pierced tubes??


Please help!

thx,

P1130=Swirl Control Valve Control Solenoid Valve

P1165=Swirl Control Valve Control Vacuum Switch

I would check the service manual and see what it says about those codes: Nicoclub.com/FSM
