Hi, I have a 1988 dodge shadow that I love and has been the best car I've ever had. we just now are starting to have to put a little money into changing original parts. Recently the car started idiling...

possibly a intake manifold gasket leak cuz if it sucks in air then it messes up air/fuel ratio cuz engine tries but cant account for extra air entering system...

My 1998 Explorer on startup idiling to high, it occasionally revs up and down while idiling. Is there a trottle position sensor that controls the idiling rpm?

there is a tps located on the intake where the inlet tube for air intake connects, it would be on the left side of the throttle body. does the trk run rough on idle? up/down sputter sometimes stall? Is check engine light on? if no light,check all vacuum lines for cracks/splits loose fit. do this by spraying carb choke cleaner on connections motor rpms will change if leak is present. also spray around perimeter of intake housing where mates with lower intake if engine revs you have bad intake gasket.I Just replaced upper and lower intake on my 98 and shazaam, runs like it should. but do your checks first,unessasary fixes are costly and **** you off.

My 2009 camry has started idling rough only when ac on. You can feel it really bad when braking, stopping, letting off the brake to go or slowing down. It only happens when ac is on. What could this be?

When the AC is switched on, the engine has to rev up by few hundred RPM to take up the additional load of the compressor.
So the fuel pump will change settings to supply the extra power for the engine.
Hence it is important that you get the engine tuned up as the idiling speed must be adjusted and then the idling while AC come ON.
Tune the Fuel with the AC switched OFF , on activation the engine gets the signal to rev up.

Won't start, engine wont rev above 2000rpm

Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle

You either have an intake manifold leak, a defective trottle position sensor or a stuck idle speed control valve.
