Fix the problem you know is 100% there--No O2 sensor then go from there. If you don't have one or planning wideband. Get an Innovate LC-1 deals all over ebay with a gauge. read about it. Wire it in and it will also act as your stock sensor to the ECU and wideband to the gauge.
Then if it ain't right go from there.
Reset battery-Pull EFI fuse for a while, or pull the battery cables off.

My car didn't want to start randomly also, once it will start and run fine, it would not start sometimes, and some time kinda start and run like crap..... It was my CTS (coolant temp sensor) for the ecu made it not start, the sensor went bad and didn't read right sometimes. And for the noise it sounds like you did the 12v mod???

have you checked the fuel pump itself? if you often run a pump low on gas it can burn up or damage the pump. also what pump are you running it sounds to me like a lack of fuel issue

i know this thread is dead, but for any one running around with this issue. my problem was that the coil pack clips where loose. its a know thing with the clips going brittle from old age.

same here
I've went through alot of things and still can't figure this out but I have hallowed out my cats because they were clogged but the o2 sensors are still there but it feels like my cars running rich which im assuming is because of no cats but when I get up near 2-3k rpms it start to jerk and seem like its not getting enuf fuel plus it kicks like a mother and at 60 mph it seems like the car doesn't want to shift into fourth or third I dont kno what gear it should be shift in in at those speeds. Changed all injector conn. Fuel filter cam sensors and still can't figure it out. Any help would be awesome thanks in advance
