So I vagged my car and got these codes:

P0300 Random/Multiple Cylinder Misfire Detected
P0301 cyl. 1 misfire
P0302 cyl. 2 misfire
P0303 cyl. 3 misfire
P0304 cyl. 4 misfire

P1602 Power Supply (B+) Terminal 30 Low Voltage
P0238 Turbocharger Boost Sensor (A) Circ High Input
P1544 Throttle Actuation Potentiometer Signal too High
P1172 Throttle Actuation Potentiometer Sign.2 Signal too Low
P0113 Intake Air Temp.Circ High Input
P0118 Engine Coolant Temp.Circ High Input
P1579 Idle Speed Contr.Throttle Pos. Adaptation not started
P1426 Tank Vent.Valve Open

[hr]
Anyone know what's up here?

I'm guessing my TB is bad/dirty, and I need to replace the ECT sensor. I'm not sure about the intake air temp. code. Is the intake air temp sensor part of the MAF? No clue about the high turbo boost sensor reading either.

My o2 sensors are probably bad too because they're reading 0.0%.

help me! please! thanks!

 

how long did it take for all of those codes to accumulate...that looks like a couple weeks worth of work...lol

I would clear all of your codes and see what comes back....do you have a CEL?

just clear 'em and take care of whatever comes back in the next couple days....how's the car running?

are you runnin a ko3 or a ko4 file?

gl!

 

The car isn't driveable. It barely idles. If I clear the codes, I can't see what comes back because I can't drive the car. The codes are all fairly new actually, I reset the codes less than 50 miles ago.

Im running a k03 file.

 

wow, well it looks like you have a good idea of where to start

definately clean your maf
replace 02 sensors
replace ECT

the boost code may have been from a mad spike...lol...you could be in limp mode

besides that have you switched over to BKR7E spark plugs gapped to .28?
you definately need to figure out your missfires

start with plugs, if all cylinders are missfirring it could simply be your ICM

gl!

hope you get this **** sorted out [&:]

 

I hope I get it sorted out too. I have no money in the bank, so repairs would go on the credit card.

Things I have already done: Replaced plugs with bkr7e's with .028 gap, checked coil packs, cleaned MAF, replaced vac tubes (some not all), adjusted fuel pressure.

I definately did have mad spikes when misfiring, so that's probably the high boost code.

I'm a 2000, so I don't have an ICM.

 

either you have a bunch of bad sensors or the ecu doesnt like you. Its claims your iat sensor, n75, coolent temp sensor, and a few other things are bad. Have you tried to reset the ecu yet?

 

Yeah I've reset it a few times, still misfires, and the codes come back.

I forgot to post one of the codes..
18010 P1602 Power Supply (B+) Terminal 30 Low Voltage

 

I dont know what to tell you. Auditech79 would know more i would think

 

IF all those codes keep coming back i would be looking at the engine managment fuse, that controls all of those functions. I had a 3.0L do that exact same thing to me after i repaired it from fire damage and it was a blown fuse.

 

See he aswered the ? and it WAS your ecu hates you...LOL!!!
