Gladly send you guys a few bucks if you call it. Car suddenly sputtered and died. Starts but dies quickly. Codes P0103, P0130, P0170, P0301, P0302, P0325. Thinking P0103 could cause the rest? Please help, thankyou.

P0130 ban 1 sensor 1 o2 sensor too low voltage code set
p0103 maf sensor high input higher airflow then expected
p0170 rich fuel mixture
p0302 cyl 2 missfire
P0325 knock sensor malfunction

first off you got quite a bit of problems I dont know if they all match up tho.

Po130 usually means that the sensor voltage is too low and the vehicle is running rich. P0130 means that the sensor is high in voltage which means its detecting a high airflow which should cause it to lean up.
P0170 usually will go on with the o2 sensor because its trying to lean it down. In your case it cant make it any leaner but it wants to go leaner. 302 is cyl 2 missfire which is odd because its on the opposite side of the o2 sensor thats reading rich.

P0325 is knock sensor and that could be being caused by the sensor being bad and cylinder 2 acting up.

Can you get me a brief history of repairs and such on the vehicle like how its running?

Check engine light had been on for the knock sensor since shortly after purchase 2.5 years ago. Thought it was because it ticks before it warms up a few minutes when cold. Ran trouble free and smooth, powerful until it coughed a couple times on the highway two days before it sputtered and died not long after starting. Couple burps on the highway, then just gave it up. Very sudden. Nothing but maintanence on to date, though i've been planning on changing the timing belt as there's no way of knowing when it was last done. Like I said, started the other day after sitting for a few days but died quickly. Thanks for your help.

First thing that should be done is remove the maf sensor and give it a spraying with qd contact cleaner to see if you can clean it up good and that may correct the problem. That ticking could be an exhaust leak. Does it kind of sound like that? That could be seting the o2 sensor code.

Yea, that's what i've been reading (maf cleaning). No, definitely not exhaust, goes away once she warms up. I'd check the vacuum advance if I had a damn distributer, this computer ghost in the machine business is for the birds. Something electronic in there certainly soiled the bed, i'll clean up the maf and it's contacts, let you know how it goes. Like dad always said, "don't take much to stop twelve volts". Thanks for the effort,

scott

Your dad is a smart mman. When it comes out its even less sometimes even.5 of a volt! Exhaust leaks go away when warm because the metal expands and seals it off! Keep that in mind.

You know what maybe pulling the battery cable for an hour and putting it back on and driving might be a good idea. Let the pcm and bcm relearn its stuff. Maybe it just tripped up.

That, my friend, is a very interesting thought (exhaust leak), I seem to remember something about that happening. After I clean the maf, i'll definitely do the power off reboot number, couldn't hurt. I'll dance around the thing with rattles at this point.

Thanks again, scott
