The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.

When I start my 2001 hyundai elantra my engine vibrates I turned it off restarted and it did it again I put my hood up everything seem to run right except for one of my belts pop ac belt maybe start...


It sounds like the idle speed is set too low, and it is taking the PCM a few moments to figure the correct setting. If the engine is new, or new to the vehicle, perhaps the engine idle speed setting is incorrectly set too low.

Engine runs good on the road,when slowing down engine dies wnen trying to idle. worsr when air is op


You said it is worse when the air is on? It is probably the ad compressor trying to lock down. The drive bearings on the ac compressor are probably almost shot causing a heavy drag on the engine

My chevy with a 350 tbi dies when i put it reverse are drive does that mean it is out of time and the rear drivers side wheel locks up when goin in reverse what does that mean


You either have a bad Idle air control valve or your injectors are clogged. Try turning the steering wheel and turning on the AC and fan. If the idle goes down the IAC is bad. A normal IAC should raise the idle a little then settle when a load is put on th engine.

2003 Honda Civic runs hot when idling.


Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.
