Could be the timing is very far off; could be the plug wires are not on the right distributor cap terminals. Could be other stuff, too.

okay...if you go out to your car
look for the airbox (big black thing on left side {driver side}) then you'll see some silver metal thing attached to it. that be your AFM. remove the intake boot (rubber) with a screwdriver on that hose clamp and stick your finger inside of that large diameter circular hole. you'll feel a flap, go ahead....push it. that flap meaures the amount of air coming through it, so the FI system can match it with a specified amount of fuel. If it sticks ANYWHERE in its travel, you need to do some work.... if you want i can pm you my number..... b |

again the car is nicely parked 20 miles away from here.. couldnt make it home, what is on the audio file is the sound i got.
but you are right, that flap was stuck last time, we freed it up by bending it and now its ok.. that WAS the problem, but how can it be the same symptoms when its not that... |

because you drive and it gets stuck again....
bending it wont solve the problem.... you will need a rebuilt AFM.... |

(IMG:http://www.914world.com/bbs2/html/emoticons/agree.gif) Sounds like very off timing. Do you have D-Jet or L-Jet? (Did 1.8s come with D-Jet?) |

Christopher,
I have a box of L-Jet parts in my garage. PM/email me and we can work out a handoff spot if you want some spares. AFM included. |

It's timing. Excessive dwell or too retarded. BTDT, just recently fixed it. And it took a "new" used dizzy to do it. The irginal kept eating points rubbing blocks.

Britt, Believe it or not yours (after I took it apart and lubed it properly with real antique Bosch distributor grease) is what's in the car now and running great. I also now have a spare dizzy all loaded and set to go in the trunk so I can put a Pertronix (used freebie) in yours and run it 'til it quits. If it does, I pop in the other unit from the trunk in 5 minutes even on the side of the highway. Christopher, I had exactly those same symptoms with the old dizzy as the dwell increased to 70+ as the points rubbing block wore down. During the course of troubleshooting I also experienced VERY reatrded timing after an initial dizzy install and that too would cause the same symptoms. It could be FI related, but it doesn't sound like it to me. Check your dwell and timing first. Start with the basics and make sure they're solid.

If the car backfired, it probably warped the flap on the AFM.
Only permanent solution is a replacement AFM. BTDT. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) |
