Rs. Sent them to deatchwerks last year for a cleaning. Turned out to be my tps harness and connectors. The tps and connectors were all withing soec but the harness is corroded and fragile so i taped it up and ziptied it so it wont move. All good now. Idle smooth as butter and pulls nicely especially in this cool fall weather. Thanks for all the extra idea fellas, gotta love this community.
