I recently got stuck in the mud on a hill & had to have it towed out today

Hi, when I turn off my air or heat there is the sound of air escaping from some where. It has always been this way, I have had the car for 8 years about, and it has never been a big problem, but I do have to replace my freon yearly. No mechanic I have ever had has said it was a problem, just the standard, "it's an old car." I was wondering if this could be a more severe problem than it seems...

I have a 79 Caprice w/thm350 and 5.7. My reverse went out, only pops in if i gun the engine, my 2nd and 3rd gears are either slipping or delayed in shifting. Is my transmission going out for good?

It only do it wen gas is not being pressed wat could it be

I have to adjust the tilt to get it to start. Then it runs in park but as I try to turn the wheel it shuts off. I need all the help I can get

The fuel pump has been replaced an map sensor been replaced an fuel filter but soon as I put it in drive it want to die down an cut off like it don't have fuel pressure

disconnected ground wire to the my Speakers. It seems like the car Will not start

What engines can I get that would be smog legal for CA, as in a turn key crate motor?

It's worse a times when it rains or hot, I replaced 3 ignition
Switches 6 starters 3 flywheels 3 fuel pumps and 2 carbs still
Have that same the problem and this not 90 caprice but a 1986
5.0l v8

I can drive for about 45 min to a hour then when I exit and hit the gas it hesitates. It feels like there's to much gas when it's down shifting it drives excellent besides that any help would be much appreciated

Car acts like there's a huge hydraulic door closer mechanism on the throttle, not allowing it to slow down the revs . . . and hence, will not allow the car to slow down safely. In addition, it is very hard to stop, since the drive wheels are fighting the brakes. I figure that it's a maladjustment, to do with its emissions system.

Does any one know how I can read diagnose code without scan tools?

I washed engine and then it doesn't start I find that its distributor module burn and I changed it after 3 days the engine run for 2 or 3 min. and it dies. Again I changed its module and it's coil but the problem is still there. Please help to fix it. Tanx
