Trace the power source from fuse to relay etc and make sure pump is working. if all checks out then check pump working and for preasue at engine. you may have a dammaged fuel line from the tank which would also cause the same problem

Give the fan a direct 12v and ground with jumper wires. If it works prob just a relay if not prob needs a fan.

could be throttle position sensor, also a hole in egr tube can cause that

Could be low on coolant, faulty water pump, or leaking head gasket among other things.

Sounds like air in system, repair any leaks flush and add universal antifreeze, and to get air out without special equipment, fill best as possible, start engine drive around block. Let vehicle set until cold. Then check coolant level again, repeat until guage stays normal

they usually just unscrew from the exhaust system and simply plug into the loom

I would take it to someone who has a scanner. NOT a simple code reader. The scanner will allow the user to see what the different sensors are inputting to the computer. A defective coolant temperature SENSOR will cause the symptoms you described. I'm not advocating to simply "fire the parts cannon" at the car. Simply giving information I know is valid. Another thing that wouldn't involve a scanner would be to check the air filter. If it's dirty it will cause the engine to run rich. Hope this helps.

The master brake cylinder may be bad. Also the flex tubes that connect the front calipers may have collapesed inside and need replacing. Does fluid squirt out with one disconnected?

This is a little confusing. Your title suggests that it's a cold weather problem, while your description suggests that it's year round. So, I'll try to help where I can on this. If it's a cold weather issue, sorry, but can't do much about that. The only thing you can do is keep your battery charged. I recommend removing it on nights you know are going to be cold. Your best bet would be to replace the standard battery terminal clamps with what I like to call, quick release clamps. Then you can connect/disconnect quickly and easilly. All you have to do, is just lift the battery out, bring it inside, and place the battery on a block of wood. If it's an issue that is occouring year round, including the summer months. Try to start the engine. Does it sound like it wants to crank? Do you get any sound at all? Depending on which it is, it could either be a dead/bad battery, or you need to replace the starter. Also, as in all my suggestions, check the wireing for frayed or damaged wires. Sometimes the most complex problems can be solved with the simplest sollutions.

Wiring is grounding the circuit.. Check the bulb socket and wiring harness where it is routed through the trunk...If there is moisture in the lens housing that can cause it also..

if it is a fuel injected you might have to open bleeder valves that run alone thi manafold on both sides going to the injectors but should have hoses so gas dosend get on manafold cause it could catch fire you can rent at auto parts store fuel injector line set kit you have to try and start while purging if you are not sure have a mechanic do it .

Even in high speed it's not what it should be? I would measure the voltage at the motor wire itself while going through all the settings. I would also check the voltage coming into the resistor block.

it would be on the backside of the engine - depending how the car was designed. The other thing is that chevy's are notorious for not having easy access to anything under the hood. keep looking you will find it - use a good wand type light so that you can see in there better.

There is no dipstick for the newer model Automatic transmission Cavaliers. There is only a red fill cap on the driver’s side on top of the transmission. The only way to check it is to jack up the car, making sure it level with a jackstand on each side of the car, and remove a small plug from the side of the transmission, underneath the car. It will be small and in an American size. It is either a 3/8" or a 7/16" size plug. Once it is removed, fluid will drain out if it is overfilled. Once there is no more fluid coming out, it is at it's proper level. If there is none coming out, then add more until it comes out and levels off. It has a capacity of about 11 quarts for the 4 speed models. The 3 speed models have about 7 quarts.

The dipstick for the 5 speed manual transmission is located on the back side of the engine. It will have either a white or yellow handle. It holds about 2 quarts of syncro-mesh transmission fluid. It is important that this fluid is used for the manual or problems will occur.

just take ur vin numbr and hav a new key done

Easiest possibility would be a clogged fuel filter. One time I had a car that was loping and it was just 2 broken engine mounts. But could be a sensor or a bad cylinder as well. Need someone to help you decide which one is the culprit.

It sounds like a mechanical problem to me , 225 psi compression seams a bit high, normally 150 to 180 . Couldn't be coils , cylinders 1 and 4, and 2 and 3. are companion cylinders share same coil. ! Do you have a fuel pressure gauge ? Do a fuel injector balance test.You don't have plug wires , you have the ignition control module an coils in what GM calls a ignition cassette , sits on top of valve cover ? plugs in center of head ?Check out some of this guys videos . ask him questions , he's a automotive repair tech. plus teacher ! he has a lot of different video on misfire detection . How to test fuel pressure injector pulse and spark with basic tools

What engine ? 2.2 l or 2.4 L. You don't say if any codes are set. no P0303 - P0304 cylinder's 3 & 4 misfire ? or any other ? No the cam sensor wouldn't cause just two cylinders to misfire. The PCM triggers the ICM to turn on an off coil's to build up an collapse the primary voltage inducing the secondary voltage . This engine is equipped with a non-distributor ignition system called the electronic ignition (EI) system. The primary circuit of the EI system consists of the following components: ?€¢ Two separate ignition coils ?€¢ An electronic ignition control module (ICM) ?€¢ A crankshaft position (CKP) sensor ?€¢ Related connecting wires ?€¢ The ignition control (IC) portion of the powertrain control module (PCM) Important: The camshaft position (CMP) sensor is only used for a misfire detection. It is not part of the ignition system. ! How to Test the Ignition Coils GM 2 4L Quad 4
