Engine Shakes 200

posted by  someone claiming to be 3VOLVOS2WORKON on  Tue Mar 16 16:45 CST 2004 [RELATED]

I'M HAVING THE SAME PROBLEM ON A '90 240. I CHECKED THE VACUUM LINES, REPLACED THE MOTOR MOUNTS TIGHTENED VALVE COVER, TIGHTENED INTAKE MANIFOLD, CHECKED DIST. ROTOR WIRES AND PLUGS, CLEANED THROTTLE BODY AND IDLE VALVE. ENGINE STILL SHAKES AT IDLE. SEEMS TO RUN FINE AT HIGHER THROTTLE SETTING. I HAVE ORDERED A NEW THROTTLE SWITCH AND INJECTOR SEAL KITS FROM FCP GROTON, SHOULD RECEIVE THEM ON FRIDAY. I WILL REPORT BACK WITH RESULTS. THE HAYNES MANUAL STATES THAT " A BROKEN OR LOOSE THROTTLE POSITION SWITCH CAN CAUSE INTERMITTENT BURSTS OF FUEL FROM THE INJECTOR AND AN UNSTABLE IDLE BECAUSE THE ECU THINKS THE THROTTLE IS MOVING". MY TPS CHECKED OUT BAD SO HOPEFULLY THIS IS MY PROBLEM.
