Question about 2000 Acura TL
While driving my car on freeway it started to misfire. I bought a OBD reader and it comes up with code P0301, P0302, P0303, P0305, P0306, P0300, and P1399. I checked coil packs and they appear ok. Not sure 5 would go out at once either. Front side of motor plugs seem to be white and no gas odor. Back 3 have gas residue. Sprayed soapy water on vacuum hoses to detect vaccum leak and no luck. Put fuel injection cleaner in gas tank and as of now no better results. TCS light also comes on? Any suggestions or ideas be greatly appreciated.
You may have a faulty crankshaft position sensor this is what controls the firing of the plugs. you may also have corrosion on the plug for the coil pack causing multiple misfires

Solved. While the engine is running disconnect the electrical connections to each coil one at a time. Disconnecting the electrical connection to a GOOD coil will cause the RPMs to drop.... when you get to the one that has no affect while disconnecting this is your culprit. Change the beast!!!
Symptoms were: TCS light, steady and flashing CEL light, shaky engine, feeling like it wanted to die out while at stop light or idle.
ALL are resolved by changing the bad coil. Reset the CEL by disco-ing the batt cable 3-5 min.

Check for cracks in the actual packs under the boot. Check the boots for holes or tears. Also put your key in ignition switch, turn to on, tap the key into the switch. Do the dash lights flash on and off? I just went through all of this with my car. Try all this, see what happens.

have your codes cleared and as soon as your light comes back on get it checked right then. usually the first code that pops up is your problem,. and can cause faulse codes to follow. check your mass air flow sensor,. make sure the breather tube is on good and no cracks or tears in it. check fuel filter also hope this helps you in the right direction
