Thought it might be Vanagon Syndrome, but will not start after dying or if it sort of does engine sputters and shakes violently and dies slowly. Newish (last fall, garaged all winter) O2 sensor, newish fuel filters and pump, newish ground strap, cleaned and inspected all rear and battery grounds, catalytic converter is also newish. Cap, rotor plug wires and plugs, and all look good, cannot find any vacuum leaks, but those are tricky for me. I cannot figure out how to remove AFM cover and do not want to break it, just to take a look. Of course any of the new parts could be failing, but I do not think so. Not sure what to check next or if it is time to tow it to the mechanic. Any suggestions would be appreciated. Thanks. |

Sounds like a TSII problem, but instead of guessing you should do a complete diagnostic from the plug on the ECU as per the manual. |

Has the fuel gone bad? Possible if it's too old. It would have a foul smell.
How are the park plugs?
02 sensor wiring. Do a search on this, very common for the fragile wire to get grounded. _________________ '90 Little Blue Truck, 2WD auto, FAS GenV 2.0 NA (AVH) |

The problem first occurred in October last year. Started with occasional bucking and surging, that got worse and then stopped us in our tracks. Would not start then or when we got it home. Towed it home and it has been resting in the garage since then though I stated it a couple times to check and it started and idled fine, but I did not run it long or drive it. Gas should be fine, but I am getting a slight gas smell after the attempted rough starts. I pulled all 4 plugs and they were fine. The oxygen sensor is new last fall. _________________ "Live every day as if it was your last for one day you will surely be right." Breaker Morant |

start with the simple things....
remove and replace your fuel filter, while you're at it, drain some gas into a clear jar. Does it smell and look like varnish? Is there rust in it? Did you change your gas cap? Does it run with gas cap off? |
