SOURCE: AC Blowing Warm Air

Leisalu,
I had the exact same problem as you described on my 02 Tahoe. I took it in for freon recharge at local mechanic shop, but didn't have mechanic check for leak. 2 months later same problem. I took it to Pep Boys and had them check for leak ($35) which they found in the clutch switch. They charged me $26 for the part plus $45 for the labor. Happy to report that the ac has worked fine since then.
Do yourself a favor and pay for them to check for leak BEFORE you waste your money on recharge.

Probox. Why is it hard to start?

A lot of possibilities. Generally speaking, you shouldn't have to touch the accelerator for it to start. If you have no trouble lights/indicators it would suggest a fuel pressure regulator or fuel pump being weak. "Cold engines take more fuel than warm engines so fuel issues present themselves earlier in cold weather. There's also the possibility of a leaking injector.

I have trouble starting my 2007 HHR upon initial start-up. it sputters but after a few seconds of that it starts to run fine. I can stop somewhere turn it off and crank it again and it starts fine seems...

this could be a bad fuel pump that has a problem from sitting over night or when it cools down enough.the armature in the pump may be worn and when its cold it has a hard time turning the pump because of it being worn and when it gets warmed up enough the clearance is closer than when cold and works fine.

Have 76' dodge 440bb that is EXTREMELY hard to start. Can prime it cold and sometimes it will fire right up, other times it takes a few minutes. Drives fine once I get it going but if I turn it off and...

First 2 things to check are the choke adjustment and operation, and the raw fuel squirt from accelerator pump when throttle pumped. You should be able to see a good squirt of gas into throat of carburetor when you move throttle linkage to wide open quickly. Choke plate ( butterfly) should be in closed position for cold start, then open gradually as engine warms up. Have you checked that as of yet? With re-start problems after warm up, may be needle and seat assembly needs replacing to retain proper fuel level in bowl for starting. If they are dirty or worn, fuel in bowl runs back out. It sounds like a carb rebuild kit might be a good idea.

Will the MAF sensor cause my 1994 nissan pickup (4 cylinder to shut off when you stop? Truck is hard to start, you have to hold accelerator pedal all the way down to get it started. It runs fine at idle....

Good Evening, if your truck runs fine at idle it would make me wonder about the mass air flow sensor, however when you first start it your idle air control sensor should open up and let your vehicle to idle up to warm idle and then back to normal. So there are a few things to check.

Problems accelerating

the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

Oil pressure high when engine cold. but fine when engine is warm

It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

Hesitation , skipping,engine cuts out when accelerating

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
