I would have to agree with sharif have you checked all the things mentioned? The crank sensor would be my first check.

 

where is the crank sensor located? im going to replace the crank sensor and vtc solenoid. if that doesnt fix it im just gonna take it to a shop. Ill have to do a search on how to check the timing. thats all i can do for now.

 

Check for power and ground at the coils and injectors. Sounds like a pinched harness and/or loose ground leading to the affected bank.

 

crank sensor is on the bellhousing of the transmission...can't miss it

 

if crank sensor was faulty car would not fire at all? check if you possibly plugged the #4 and #6 coil harness(2 located on back side of driver side) back to the same harness- can be easily mixed up. I did it to mines and caused me to burn a cat out.

 

this problem did not happen post spark plug/ coil checkout. so i dont think they are switched. at least one of the cylinders would be firing anyways, if that was the case. if you read back i checked which cylinders were firing by pulling the coils out while the car was running. all the drivers side cylinders had no effect when i pulled the coils. and all the passenger side coils made a noticeable difference when pulling them. i also switched the coils to see if the same thing happened and it did. so all the driver side cylinders are non-contributing cylinders.

 

just bought a new crank sensor. gonna change it tomorrow. keep you guys posted. thanks for all the replies.

 

^if you need to check timing, get a timing light.

 

changed the crank sensor and the cel still flashes. and the ecu was reset. left the battery disconnected overnight. guess i have to check timing. if thats not it i dont know what else to do.

Anyone ever hear of technosquare reflashes going bad?

 

Have you tested the driver side bank harness power/ground yet?

 

Listen to the previous poster...check the connectors to your plugs and your injectors. I can't tell how many times I've seen them swapped around. After reading all the posts clearly now, and that flashing cel my money is on this. .

Or mechanical timing is off.

 

where is this harness located?

 

Also check the coils them self for bubbling I have see where the coils them self burned out due to bad ground.

 

Trace all of the wiring for the sensors and anything else leading to that side of the engine; you have ruled out just about everything but that. I'm guessing there is a bad connection or a broken/melted wire somewhere - just don't know what else would affect just one entire bank....

 

what about a fouled O2 sensor? anyone think that could be it. im gonna try swap the upstream sensors and see if anything changes. then swap the downstream sensors and see what the outcome is. if that doesnt change anything ill just have to look for bad connections and burnt wires. this sucks.

 

I would assume a fouled O2 sensor (the front one) would make your AFR's go wacky and throw a lean/rich code but not shut down all driver's side cylinders :|

^^ This.

 

crap. I was afraid of that. It's going to be a looooong night. I hate wire chasing.

 

careful if the cel starts to flash b/c its a sign that the engine is misfiring enough to cause catalytic converter damage. Do you have a strong odor of gas? Did you run a compression check?. Pull the plenum off and pull all the wires to the coil off and trace it. Might have it burned somewhere behind the engine bay and firewall

 

yup strong odor of gas. compression check is good. just gotta go chase wires. and i dont have any cats.

 

I had the exact same issue. Driver side not firing and the car still ran. Compression check was good and all the coils, plugs and injectors were fine.

All I ever got was the "multiple misfire" code and nothing else.

Best of luck to you.
