I'm still having weird engine issues. It was bucking really bad until warm up, especially in higher RPMs. I did a tune-up which helped but didn't solve it, engine would still buck while cold at higher RPMs (3000+), and at about 3500+ when warmed up. Fiddled around some more this weekend, resulting in amazing improvement; now instead of bucking, it just kind of feels like it's dragging like a dog scraping its butt on the carpet. Yes, at higher RMPs, and regardless of what gear I'm in. I've done the following thusfar to resolve this issue:
•replaced thermostat •replaced engine temp sensor •replaced plugs, cap & rotor, air filter (improvement #1) •replaced fuel filter •seafoam gas treatment, seafoam vacuum line (discovered leak in gasket around header pipes) ![]() •removed intake housing, cleaned the hell out of throttle body/plate •realized that did nothing, REMOVED throttle body, discovered diamond mine in carbon deposits, cleaned thoroughly including all those tiny little vacuum tentacles ![]() •whatever that thing is called (is it just the intake?) that the throttle body is attached to, well I sprayed the HELL out of it and soaked a rag too and did my best to clean it out. It looked like a stalactite cavern. Result was a marked increase in throttle response, made my car feel young again. But still dragging ass on 3000+ RPMs regardless of gear. What is that thing the throttle body attaches to? Should I attempt to remove the cover from it so I can get rid of the rest of all that carbon build up? Is that my problem? Does anyone have any other ideas? PLEASE? Thanks... -------------------- ![]() |

There's no CEL. I failed to mention I reset the ECU a while back also, just to see if maybe I could "trick" it into doing things my way.
![]() It does it all the time, less-so when it's warmed up, but consistently at 3k+ RPMs. I talked to a Toyota mechanic last night (the guy who hooked me up with my shiny new strut bar! OW!) and he also suggested the plug wires. I think when I get paid again I will buy new wires and see if that helps any. Any other suggestions as to what else I should check are MOST appreciated! I want this to be the smooth-running powerhouse ![]() This post has been edited by GriffGirl: Jan 23, 2008 - 11:08 AM -------------------- ![]() |
