LIke stated before, i'm gettin hesitations and sputter all throughout the power band. And sometimes it just sput sput, dies on me! whats wrong with this picture folks. It's not the 3800 it happens whenever. I changed plugs today and i will check them tomorrow see if they are foouled. I am going to change the fuel filter tomorrow as well. If there is anything else? Please let me know

BTW, not in ft lbs but how hard should a spark plug be torqued? thanks,

Evan

 

I recently had intermittent hesitations / bucking regardless of rpm, which became less intermittent as the weeks went by. My tps was faulty. You can see if yours is had it by wiring up a multimeter onto the throttle sensor input of the ecu, and getting a passenger to watch the voltage and see if it spikes up and down all over the place during the hesitations. Mine dropped to 0v whenever a buck occured. Pin inputs of the ecu can be found in the manual at www.iluvmyrx7.com

Sweet, thanks alot Charlie. I hope thats what mine is....TPS can't be to expensive?

 

anyone else?

 

A new tps here in aus is about $300, which would be about $150 u.s I guess.
