ok well started like this i went and change my spark plug on my 95 sc300
a complete tune up. so before i put back the throttle body and manifold
i cleaned the throttle body and the egr passage so brand tps brand new 1dle speed control brand new throttle body gasket and intake manifold gasket
to make a long story short after 3 days of driving the car
my rpm boost up to 2000 and check engine light came on wont even turn off
i check for vacuum leaks none check all the connections its good
i need help here peoples im about to give up on this soon not unless if anyone has an idea or has happened to them before
my guess is the ecu,maf , but theres this one solenoid just right above the
fuel pressure regulator its ticking really loud so please help
you can e mail me at lb_engineering@yahoo.com thank you

 

i dont know what the probelm is.. but idling at 2000 rpm.. lemme tell you.. when i removed the Tractiong Fuse off my aristo it was idling at 3000 rpm.. !

i suget.. check the fuse panel... then reset the ecu.. if no use.. then get it diagnosed !

Thanks.. wish i could help more !
