its surging
 

when i start my car in the morning, and run it about 10 miles and stop at a stop light the motor starts surging. the rpms range up and down 500-1200. it only happens after it runs for a while. and seems to only happen when i sit facing up hill. i dont konw if its a fuel problem or what.

Take the off your your trottle body and everything attached and you maf meter and spray with carb cleaner. One of the parts attatched to the throttle body has 2 holes and just fill it with carb cleaner. So basically just clean everything. Also be nice to the MAF Spring!

I know all these parts have names but i'm not going to look them up now...I'm at work..

Clean the MAF Meter too. Check your tps voltage.

no leaks that i can hear and i have already tried sea foam. and no cam. i will try sprayin carb cleaner around the intake to see if the rpms drop.
