There's a number of other things it could be. Faulty O2 sensor(s), faulty fuel injector(s), failed catalytic converter, poor compression, etc. These articles ought to help - P0303 - P0305 - P0306

"I compression started my 99 beetle but when i put it in gear and let the clutch out it dies and or loses power. now whenever i put it in gear and let clutch out it dies even though battery is good.


So if I'm reading your question correctly, your problems started when you had a dead battery and had to compression start your Beetle. Is that right?

Now, presumably, the battery has a charge and you are able to start the car with the starter, but it has no power; so much so that it won't run when you try to put a load on the engine.

Unfortunately, there are a huge number of problems that can cause this kind of behavior. Is your Check Engine light on? If so, it would be extremely helpful if you could get the trouble codes from the On-Board Diagnostics (OBD-II) port.

Otherwise it's going to be a trial and error process to pin down the issue. An engine needs three things to run: air, fuel, and a spark. Since the air and fuel are all computer-controlled on the Beetle (and pretty much every car currently being made), the only thing obvious left to check is the spark.

The only time I've had a similar-sounding problem with my beetle was when one of the two coil packs went out. Since each coil pack handles two cylinders, one of them going out leaves you running with only two pistons. Get some heavy insulated gloves and try pulling the spark plug wires one at a time and see if any particular cylinder is affected. If the source of the problem is a bad coil pack, then pulling the plug wire on two of the cylinders won't have any effect, and pulling the wire on the either of other two will almost certainly kill the engine.

If all four plug wires act the same when you pull one, then it's likely something in the engine management system, and should have an indication in the OBD-II trouble codes. But without more information, it's impossible to figure out what's going on with your Beetle.

Still trouble with my 2001 Ford Windstar after replacing spark plugs and wires. It always starts instantly though still running a little rough. Sometimes the power doesn't kick right in to climb


I would suggest you run a compression check on this engine and also have the coolant recovery tank tested for the presence of combustion gases with a gas analyzer, any gases would indicate a leaking head gasket. Any engine cylinder that is lower than 5% of the highest reading cylinder in pounds per square inch has a problem like a scored cylinder or leaking intake or exhaust valve seat.

Hello i have a GTI its a 2.0L manual transmission, i have been having problem after problem thus far. Current engine codes PO422, PO300,PO304,PO303,PO302. I do not have a code list to see what these are...


I think that PO422 is the Cat Converter, it may be bad or may be just the O2 sensor.
The PO300, 302, 303, 304 code have to do with the ignition coils or wires. (302, 303, 304 means there are ignition /firing problems in cylinders 2, 3and 4). If your lucky just the wire and new spark plugs.
Google "engine codes Jetta" for more on web. Good luck.

03 windstar misses and sputters when it rains,eng lite flashes then stays off 4 a while.then goes off. when dry out it runs great.is it the coil pack


Could possibly be the coil pack has a crack in it, could also be plug wires have cracks in them as well, sounds like time for a tune up. Recommend replacing plugs and wires, and if that doesn't solve the issue then spring for the coil pack. Scanning the computer will tell you what code you have to help point you in the right direction as well. If you have any p0300-p0306 codes those are all misfire codes.p0300 is random multiple misfire, p0301-p0306 are individual cylinder misfires.

99 ford windstar (3.8)seems to misfire randomly when idling and can feel pulsations while driving


clean the MAF sensor first and also add some Chevron Techron fuel injector cleaner to 1/4 tank of gas. You may have a dirty MAF or a partially plugged injector.

Misfire #3 cylinder


Has anyone found the problem? My 2003 has #3 cyclinder misfire and I have replaced the plugs and wires. It runs rough at idle but smooths out at highway speed. Anyone have any knowledge on this? This sounds like a common problem.

CHANGED WIRES TO PLUGS WANT VERFIY PROPER LOCATION TO COILS


have a look at the coil pack... it is numbered... now if it's like a 95 windstar the engineers had a sense of humour. it is 1 2 3 down one side then 4 6 5 down the other.... i didn't notice this when i changed my coil pack and couldn't figure out why it was missing.
