Took the car wirh 147,000 miles on a long ride (380) miles to and from. Car loses about 400 RPM in Idle and hesitates on acceleration. Replaced Water Temp Sensor due to code. Check engine light now off. Have not had a tune up in a while. Could it be that or something more serious?

Thanks for your help.

 

clean your IACV (idle air control valve)
clean air intake filter
clean throttle body
tighten throttle cable
check spark plugs see if it died

just naming out few basic maintance...

 

automatic or manual? check ignition coils as well idle is about 600-700rpms

 

maybe injector went caca on you?

 

killcrap, LOL, what do you mean about the idle at 600-700 rps. Is that normal or bad? Does is signify the coils are going bad?

 

normal idle when engine has warmed up is between 550-650 for manual and 600-750 rpm's for auto. if your car is hesistating then the ignition coils are bad i believe. ohm them out they should give a reading of 1 (infinite resistance)

 

Maybe the fuel system? Do you use any kind of Fuel syetem cleaner?

 

Thanks. At this point I think I will try a tune up. Can anyone supply list of items for a 120K tune up? Can I use Bosch Plantinum or must I use the expensive NGK plugs?

Thanks

Bad fuel injector, EGR valve and got tune up. This fixed issue.
