Hi! You may have a faulty MAF (mass air flow) sensor. The MAF has big contribution on engine performance specially the idling. Have it replaced and you'll be good. Hope this helps and thank you for using FixYa!

Why wont' my a/c system blow cold air after adding freon?


Hmmmmmm, There is a lot more to AC systems sometimes.

Is the clutch on the AC compressor turning when you have the AC on? How much pressure is currently in the system? Does it have AC in the back of the vehicle?

The most common reason for this is the front seal of the compressor leaks, The leak is hard to track down as it is often gas and no oil or residue.

I have a 1997 jimmy and it cranks up fine but it starts bogging down when i am driving and when i try to climb a hill


You may have a clogged up egr valve. When the egr valve gets clogged up with carbon, the truck will run rough, surge stall, and be very anemic on power. Is the service engine soon(check engine) light on? I've dealt with this issue before, and those 4.3 v6's tend to get egr issues. Try this: when it bogs and runs rough, stop truck, open hood, and tap on egr valve base( where it bolts to engine) if rough running clears up, there's your problem. Egr valve is located on front of engine just to the rt of alternator bracket.

Sounds like an issue when fluid gets hot, I'd start with a filter/fluid change.

I personally shy away from tranny additives, use only as a last resort to get a vehicle drivable to trade in (on a cash for clunkers program. (((SMILE))). )

Ground coil or remove plug wife away from number one spark plug. Place finger in fron of spark plug hole while some bumps the starter. When the air for the copression pushes finger off hole stop started . Align the timing marks,or insure that they are close. Place distribiator back into hole with the cap off pointing to where the wire for number one plug is going to go. bolt down dist. and replace cap.  Your timing wil be now close enough to start or if not rotate it slightly and try again.
