Ok i have a 95 tahoe had a bad a/c compressor changed it and now when i start the truck it idles really bad it sounds like it is camed but its not. After a minute it adjust the idle on its own and the service engine soon light pops on. I have noticed a loss in power when gettin on peddle. I am lost could it be because i didn't refill the freon.

 

Is the new a/c kicking in and out like it should and when it does is it spining like it should.

 

The ac is working fine. The truck had no problems at the time i changed it. Its just odd that i change the ac com. And then the truck doesn't start right and has loss of power.

 

Huh Thats strange I wish I could help cuz the only time Ive had a/c probs is when mine froze up and when it would try and turn on just the friction from the belt trying to turn it caused rough start and idle and all that jaz but that lasted but two seconds before it started to smoke the belt so I just turned off the a/c and then later unpluged it. Sorry

 

IM confused i have built 9.50 sec. Drag cars and never saw nothing like this ill have it tested tom. Hope it gives me something to work with. Hope a wire is just split or something.
Thanks anyway

 

any chance you may have knocked a vacuum line off somewhere and didn't see it?

 

check your ect make sure its connected should be right up by the compressor check harness from ac compressor this unit is monitered by the pcm and adjusts idle and other functons see what code it through with a scannner and if this is a result of a compressor install take it back to the shop that did it and raise a little h... if they dont want to check it out something around the line of fine i will take it to a certified dealer and if it is found to be a direct result of your workmanship then you can count on recieving there bill including time and loss of wages and expences incurred do to your neglegence and lack of cooperation
HAMMERGONE!!

 

ok i got it. it was only a dirty plug on the ac com. it was affecting my idle control sensor. thanks for the help.

 

i was just going to say check the wiring... sounds like the A/C is turning on but the computer doesn't know it to adjust the idle... outstanding. i miss my '95 2 door
