So far nothing works...
It seems like everytime i think i've fixed a problem another starts... It all started a couple months ago when my CEL came on for a Missfire. Probably have read my posts. Went through everything trying to fix it but can't seem to get the car running right. So heres what ive tried and what problems i have:
1. Missfire Cylinder 1 - Tried spark plug, then coil, then seals, and recently the injector. After replacing the injector car ran amazing no miss, so much more power and responce. But then it all went away and more problems.
Now: The miss is back but have a very strong gas smell from the exaust dont smell it when I'm moving but fills the car when im stopped but people say they can smell it behind me when im moving.
Also since the replacement of the injector i started throwing the code 0201 - Ignition signal circuit and I need to pump the gas to get my car to turn over.
Today when i went to bring my friend home my car started dropping rpms like crazy and stalling out and is idling at like 350 rpms so i put it in the driveway and stopped driving it but dont know what to do.

Changed fuel filter? Changed the o-rings on the injectors?
So you're getting 0201 and 0608 (cyl 1 misfire)? Check the Crankshaft Position Sensor (REF)

0201
Diagnostic Trouble Code 0201 indicates a problem with the ignition coil and power transistor. The ignition signal from the Engine Control Module is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.
The malfunction is detected when the ignition signal in the primary circuit is not entered during engine cranking or running.
The items to check include
- Harness or connectors (the ignition primary circuit is open or shorted.)
- Power transistor unit built into ignition coil
- Condenser
- Crankshaft Position Sensor (REF)
- Crankshaft Position Sensor (REF) circuit
A misfire on any individual cylinder should set a code, and a problem with the CPS should also set a code.
I would have expected to see DTC 0201 along with one of the following DTCs.
0407 - Crankshaft Position Sensor (REF)
0608 - Cylinder 1 misfire
0607 - Cylinder 2 misfire
0606 - Cylinder 3 misfire
0605 - Cylinder 4 misfire
0604 - Cylinder 5 misfire
0603 - Cylinder 6 misfire
You didn't get one of these "companion" DTCs, and that is puzzling. Maybe one of them will show up in the next few days.

Did the MAF cause the strong gas smell though? and what about changing this injector triggered the gas smell. I checked all the sparkplugs and each cylinder is firing so its not spark related unless timing is off... i have no clue

lanky, i have the same problem (as your first problem) with my car.. you say it was the injector? ill look into that thanks.. as far as your other stuff im not sure, but i have the strong gas smell too and i know my front-most 02 sensor is dead.. maybe thats the cause? just a thought. good luck

I was throwing a front right o2 code but wasnt sure if that would be causing it. Ive thrown the rear o2 code but when i replaced my knock the o2 code went away but if thats the cause for the gas smell that may be it.

Had the code for front right o2 sensor. Checked it with a multimeter today and got the correct reading according to the haynes manual could it still be causing me a problem. is there another way to check it or should it be fine. And can any1 diagnose that smoke... ive never seen it so bad and smell so strong of gas on any other cars

I just dont understand how when i replaced the injector it fixed the missfire only problem i had was when starting the car i had to pump the gas but i just thought that was air in the lines but it never went away and now i got the smoke and strong gas smell and the miss is back. The miss must be fuel related in someway since it was fine for awhile with the new one.

FWIW, if you're smelling gas, it might mean that it's not getting burnt? Is the car missing or idling smoothly? I believ you said you replaced an injector? Is it still working? What about the coil pack? Also, I DO know that if the mixture is too rich, that can ruin the sensor and/or cat

I'm thinking it's still a fuel problem, maybe the injector O ring was torn or not seated correctly.
The gas smell doesn't have anything to do with your O2 sensor though I can promise that.

That's white smoke from your tailpipe. White smoke is almost undoubtedy coolant. Fuel would be more black and oil would be a little blue.
Has the car been using oil? how much do you have to add in how long?
What about coolant?
And gas smell does have to do with the O2 sensor. If the O2 sensor reads lean, it will richen the fuel/air mixture.
I think by looking at your picture i'm like 75% convinced you are burning coolant and 25% convinced its an oil problem.
You need to do a compression test and a cylinder head leak down test. Try using a heavier oil like Chevron Delo 15w-40 and see if the smoke is less. If it is then its probably an internal oil leak.
Personally, i'd take the heads off, check the valve guides and oil seals and put on two new head gaskets.
in any event the smoke looks like a major problem thats internal and not related to your O2 sensor.
