That must be the crankshaft position sensor. That's what tells the car when to fire. There usually on the bottom of the motor but it's sounding like that's your problem. Could have a bad crank sensor

SOURCE: missfire

Have you replaced the coil yet? I assume by all 4 cylinders misfiring you mean P0300 Random Misfire? It could be a number of other things - a faulty fuel injector, coil, etc. Read this article for more info on random misfires - http://www.obd-codes.com/p0300

SOURCE: trying to find where a ground wire connects to

Wire could go to rear of cylinder head. Going from the firewall to the master cylinder really does not make much sense as that assembly is bolted to the firewall and is grounded there. Generally most systems have multiple ground points, which is why you likely don't have any problems other than finding a home for that wire. On lots of vehicles I've owned, when there was a question about reliable grounding, I ran a 12ga or heavier wire from the battery to engine, firewall, dash and fenders, independent of all factory grounds. It's overkill, but I've never had a ground problem either!

You will need to check the contacts where the bulb inserts for arcing, causing a short. Test for power and ground at the conn. 2 b sure you have power there. If this is the case you will need to replace the light assembly.

How many O2 sensors does a 2005 Chevy Cobalt base model 4 cylinder have


Oxygen sensors are identified by bank and sensor position. Sensor 1 is always pre catalytic converter, sensor two is always post catalytic converter. If an engine is a 4 or 6 cylinder engine the whole engine is considered bank 1, if an engine is a V6, V8, V10....., the engine bank containing cylinder number 1 (first cylinder in the firing order) is considered Bank 1, the other bank is considered Bank 2. Interpretation Oxygen sensor designation B2S1 refers to Bank 2 Sensor 1, it will be the sensor on the engine side of the catalytic converter in bank two. Check this link to determine the cylinder that contains cylinder number 1. http://www.wellsve.com/custom_searches/ds_firing.php Wells Search Parts Catalog

If the wheel is turned in either direction, pull the whell in that direction and try getting the key out. If that doesn't do it, try shifting the automatic transmission from Park back to drive, and then to park again to disengage the interlock.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
