Still having problems

Thought I had fixed my problems by replacing the MAF, went away for a few days and now it's been back for awhile.

There's shuddering with the engine during idle and now during any driving. Makes the car shake and pretty much sounds like its not running on all cylinders. SES light blinks constantly now whenever the car is on. The idle goes to hell, almost stalls but revs itself back up. My OBD-II port had no power when I went to autozone so today I went through all the fuses, found the cig lighter was blown and replaced it. Going back to autozone tonight after rush hour and will update accordingly.

Also I checked hoses and connections to see if any were cracked or off, all were good and couldn't tell about a vacuum leak.

Wondering if anyone has a clue before I go later tonight as to what it would be? Plugs/Wires/Coils?

flashing ses= multiple cylinder misfires. autozones scanners arent the best... any way of getting it on a better scanner? check the coils for corrosion.
 
Multiple cylinder misfires... well that sounds great haha.

Nope I don't think I can get to any better scanners, I could call a local mechanic to see if I could get in tomorrow but as of now it looks like just autozone's gear.

After I head out i'll pull the coils and check them, thanks
 
Sounds about right...Swap the injector to another cylinder and see if the miss follows. If it does it is the injector if not it is in harness for the injector.
 


There are 4 10mm nuts one on each corner of the the fuel rail and a 13IIRCmm nut in the center on the top. Then the whole fuel rail pulls up, might take a little force. Then there is a metal clip holding the injectors on pull that out then they pull off.
 
Funny thing, i swapped out the injectors, cleared the codes, all is well now. Drove for about 30 miles and nothing, idle was perfect, WOT was fine all the power was back to normal and best of all no SES light flashing at me.

Weird thing is the injector had a crack on the side of the nozzle, but it seems to not be effecting anything... i don't want to drop 80 on a new injector unless i have to.
