Possible culprits: A bad headlight relay Have the relay tested or replaced. It could be that the switch for the main circuit is intermittently stuck-closed. A closed-circuit in the light switch or relay getting grounded Eliminating a bad relay would leave you the possibility that the relay is being activated when it shouldn't through an intermittent ...

Oil leak is unrelated. You should fix that. (: There are various possibilities: The temperature gauge is faulty or the sender that sends the gauge the temperature reading is. Test: Block part of the front of the radiator with a piece of cardboard. This will force the system temperature to raise. Drive around for a little. Watch the gauge. Does it go to ...

It is worth removing them, cleaning them and setting the gap if you don't want to replace them and they are still in good condition. Spark plugs will be a scheduled item to replace, like you said, for preventative maintenance. Unless the plugs were very dirty, worn or had a larger gap, you shouldn't notice any difference.

I've seen this behaviour on a car with a hairline crack in the fuseboard. The result was that sometimes the car would run beautifully and sometimes it would all but die and bog down on the throttle. This was because the ignition system wasn't always receiving a good strong input power at it's low tension side. Sometimes it was, sometimes it wasn't. I'm ...

You mentioned the coil and leads, but I would inspect the leads for cracks etc. They may test within spec when removed from the car, but when vibrations start or they bend and flex, they could leak voltage. Black plugs - as you know - can be from one or more bad leads. I would remove the fuel filter and inspect it vigorously...I would shake it and bang it ...

UPDATE: We pulled the engine and trans today, and put the correct flexplate on, which definitely has a different geometry and sits closer to the trans (i.e. not pulling the torque converter out). There was no evidence of spline or seal damage. Put it all back together and ... it runs, drives, and shifts perfectly. So my theory, #1 below, was correct. Also ...

As a tune up you can change the spark plugs in between 80-100, the ones that come stock are good ones so doesn't need replacement until they go bad or reach 80k, we at our shop replace them every 100k along with the timing chain or belt. In your case the car will have a tiny I4 motor so the spark plugs are right on the top, the spark plugs would only cost ...

Solved it. Removed the thermostat, dropped it into a pot of water and boiled it over the stove. The thermostat that came out of the car didn't open, the one from the junkyard did. Reassembled, filled the system with water, purged the air and revved the engine at idle. It took longer to reach operating temperature, it didn't overheat and the fans didn't go ...

My suggestion is to look at the throttle body, specifically at the throttle position sensor (TPS). You need to see if it has the right output. You can either do this by looking directly at the computer (through an OBDII device), or by measuring the output at the TPS itself using a multimeter. In either case you'd be looking to ensure there is a clean sweep ...

It looks like a stabilizer bar link. Hard to tell for sure due to the fact that the image is so small. I had to zoom the image 300% to make it out. If you take a more closer picture focusing the part in question then I can confirm it. It is a component of your suspension system.

It is the drop link that connects to the anti-roll bar. When you go around corners, the car will naturally lean in the opposite direction to the turn. The anti-roll bar limits the amount the car leans. Leaving this disconnected will seriously affect handling and could cause an accident.

Something wrong in the fuel enrichment for a cold start. Too much fuel during the start and warm up, but in normal operation the mixture is correct and it burns soot from the plugs. The ignition is an" innocent bystander ".

A bad head gasket can also generate bubbles in the overflow tank, and would certainly lead to overheating and coolant loss. You can get a relatively cheap kit to test for exhaust gases in the coolant (or any number of other methods to test the head gasket.) If it's a very minor leak, it's possible that it partially seals when it gets up to temp, so the ...

If your alarm flashes the headlights, then the electronics in the alarm could also be at fault.

OK so it blew a 15 amp fuse. Thanks for the help. I also want to know how it blew a 15 amp fuse so next time it won't happen. Does the radio actually draw that much current? Or did I short circuit the outlet by plugging the USB charger in? If you could help me figure out why it happened that would be great.
