engines have 4 components, air..sparks..fuel...exhaust.start with the cheapest and work through until problem solved...ie ht leads,when were they changed last or plugs, same thing.....even a lowly air filter will have a massive effect.(acts like a choke)

Hello hippy3369: My name is Roger and I will help. If the controls appear to be working and the air is fixed on the floor and out the defrost vent. Your problem most likely is under the hood of the car. Open the hood.Look fr a vacumn hose from the intake manifold and the fire wall. This hose should be around 5/16 of an inch. It wil run from the engine to a vacumn tank . Look in the center of the firewal just on the passenger side of the brake booster. The hose is prone to deteriation and will break causing a vacumn leak. This leak is the source of vacumn to the A/C controls. Replace the hose and you should be back to staying cool. The control head could also be the problem.But the most likely is the hose under the hood. Should you need further help please just ask. Please rate the answer as this way I know it was useful. Thank You for using Fix Ya. Roger

Check the ground to the fuel pump. It may be making bad/intermittent contact, causing the circuit to overload.

If you are trying to remove it, you have to use an oil change pan to catch the trans fluid. loosen all the bolts (15 of them if I remember) and then start from one end only and take them out. This will cause the fluid to flow into the pan, just make sure the catch basin is large enough. Good Luck.

Try cutting back the fuel intake. There should be a screw close to where the fuel line enters the carb. If there is a fuel injector It could be a few different places. GoodLuck And PEACE
