It will have to be fixed before you drive it very far. If the battery light is on the alternator is not charging, your not going to make it very far before the battery goes dead. Your local parts store will be able to test the alternator on the car, most if not all will do it for free. Based on the battery light I am confident it's the alternator, but ...

I checked a known good waveform (cannot copy here, copyrighted). Yours is shifted just a bit to the right. Around your frame 95 that cam sensor vertical line should exactly bisect the horizontal line on the crank signal. Most common failure for a small shift is bending of the locator roll pin on the cam pulley.

The most common cause of this symptom is sticking of the automatic idle control valve. It is located on the throttle body right above the throttle position sensor. The idle control motor opens and closes to allow more or less air to bypass the throttle blade. The more air it lets through the higher the engine speed will be. It is controlled by the PCM. When ...

It sounds like you've got a leaking headgasket - the oil is leaking into the engine, which is why the machinic couldn't find the source (though I'd except any decent mechanic to spot HG failure symptoms). Does it also tend to smoke a lot? Particularly blue-ish smoke. You've spotted oil in the coolant, have a look for coolant in the oil (a thick mayonnaise-...

The thermostat is a valve that helps your engine cool correctly. When the engine is cold, all engine coolant flows within the engine block; the thermostat is closed in that condition. As the engine gets warm (generally at 195 deg F), the thermostat opens, and hot coolant flows to the radiator where it is cooled. As you might expect this is important in ...

This is a common problem on some Ford Focus engines and is caused by a split air hose (it could be a crank case breather hose). The split will open up while driving, then stay open for a while when the throttle is closed, which causes the same sort of symptoms I believe you are experiencing.

Found the answer -- it's the transmission vent.

On that MY Neon an "intake air gauge" doesn't have anything to do with the charging circuit. The amount of amperage produced by the generator is controlled by Electronic Voltage Regulator (EVR) circuitry within the PCM. EVR circuity is connected in series with the generator field driver terminal and ground. A Battery Temperature Sensor (BTS) is located on ...

I would suggest removing the linkage from the shifter and move the linkage directly at the transmission into second. I believe it is one arm. In and out is like moving the shifter side to side. Rotating the arm puts it into the individual gears. Play with it and you should be able to find reverse as it sounds different when you go in. Put it in second, ...

I had a similar problem some years ago and it turned out to be a blocked breather on the fuel tank. Next time it happens to you, provided you are somewhere that it's safe to do this, jump out of the car and pull the fuel filler cap off and listen around the neck of the fuel tank of a whooshing noise, as though air is being sucked into the tank. If this is ...

If you are looking for a true dollar cost per km, then do a stock rebuild on the engine. The small amount of abuse from the hp gain you are talking about can be easily absorbed by internals of a stock engine. You just need to ensure you are doing things right. There are several things you can do while rebuilding an engine which will help with longevity: ...

Take the starter off, take it down to your nearest AutoZone/O'Reilly's/Checker/etc. auto parts store and have them bench check it for you. I'll bet your solenoid is no longer functioning, and therefor your starter has quit working.

If you say all the hoses and clamps are in good order, then the only other things that come to mind are the wastegate and exhaust manifold. Either the wastegate is opening too soon, or the exhaust manifold is leaking from the gasket or a crack. This would mean that either you lose boost too early, or you never get enough boost in the first place. Or, if you'...

The same thing actually happened again a year later. It was the same situation where the alternator wasn't putting out enough voltage to charge the battery. I took it to a mechanic and they noticed that the wire(s) connected to the alternator were burnt. After replacing the wires, everything worked like normal again. Putting two and two together, both ...

The oil in your coolant is significant. There are several places oil can enter the coolant, head gasket as mentioned, but also a cracked head or block, a failing oil cooler, as well as accidental filling. If you have had cooling system work done and an oil contaminated water can was used to fill the cooling system for instance this would have introduced the ...

The flooding problem is probably the funky gaskets used around the tail lights. Get some silicone, take the tail light assembly off and on the left side run a bead of silicone. The water runs down the trunk track right along the left side of the gasket and ruins it's properties over time. The gaskets cost around $12.00 on ebay but from what I've read ...
