SOURCE: Car struggles to get into first gear after it has warmed up.

You probably have a problem with your CV joints. There is a device that helps in the shifting of gears that needs looking at. I assume it shifts to the other gears when it is warm ? How many miles do you have and are most of the miles on the highway? I hope this isn't leading to a transmission breakdown. Have you had the transmission serviced regularly and filter changed?

SOURCE: idle is too low, car dies, engine runs fine

An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The car computer or ECM (electronic control module) receives information from various sensors and will output signals to adjust the IAC motor in or out to adjust engine idle speed by controlling engine idle air.
An IAC motor is highly susceptible to carbon and coking build up; if an IAC goes too long without cleaning it can cause stalling and poor idle quality. Some cars are designed with a large vacuum transfer hose that connects the intake manifold to the IAC (idle air control) motor. If a broken or dilapidated these vacuum lines can cause the engine to lose vacuum which will allow the engine to run rough and die. 
Inspect all engine and accessory vacuum lines to look for missing, torn or dilapidated lines and replace as needed. To check the IAC motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the IAC should move in or out. 
If the IAC motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the IAC motor is removed clean (use aerosol carburetor cleaner) the passages the IAC uses to control idle air speed.

Good luck and hope this helps

SOURCE: frequently will crank but not start

the problem must be with the batteries. check the voltage levels of the battery using a voltmeter. if it goes lower that 10v and fast dying, then replace them. and also check the alternator charging the battery for any charging problem.

SOURCE: 1983 honda acc cold start wont stay running when cold idles rough

try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.

Why does my '88 Mercury Grand Marquis w/5.0 stall when put in gear?


I am thinking that the idle rpms are too low and the tune up is not good enough to compensate for the drop in rpms when the transmission is engaged
normal idle rpms on an automatic should be around 850rpms as they will drop 250rpms on gear selsction
any idle speed around 500 rpms will die when fear is engaged

What can I do to get my 1975 dodge RV with 360 2 bbi from stalling when put in gear


the other setting for the idle is not done you have the curb idle done but when you drop it into gear it stalls out go to where the choke is and adjust it you'll see a screw there move the throttle lever back and forth so you can see where it is that screw will increase the fuel going in to keep it running raising the rpm's make sure the choke plate is in the proper position to it could be closing all the way blocking the air out which is needed for combustion in the cylinders

I bought an 89 dodge spirit, and it wont keep the battery charged has had multiple new batteries put into it and it also stalls every time its put into gear what could be the problem


Most probably, the AIC stepper motor is bad, one way to kno, is when the engine slows at idle when you swithc on the air conditioner, and the Idle automatioc control does not correct the RPM dropping from the increased load. An engien that does not maintain correct and stable idle cannot maintain the battery charged, but it could have multiple issues.

Can't adj..clean your IAC. Idle Air Control valve, or possibly replace it. The Computer adj's you idle by this valve moving in and out, it gets carboned up and does'nt move like it should.

The idle drops when i put it in gear almost stalling the engine


That is normal, in park or neutral there is no resistance on the engine when you put it in gear there is resistance because the car wants to move. Also when you turn on the ac that turns on the compressor that is run off the belts of the engine so it puts more resistance on the engine. Low idle is not a problem unless the engine dies.
