Gang, I need your help. I started out just running rich. So I made a very small adjustment to the AFM to lean it out. I also did a tune-up (cap, rotor, plugs and wires) No points (Compufire). I also replaced my ol faithful Bosch Blue Coil (12 years old) with the best I could find in a day (Standard Brand). Now I am running rich and with a nice case of hesitation and blubbering. Idle is good, but the minute I pull on the throttle a slight decrease on the RPM for a second then it picks up and blubbers at what ever point I pull the throttle up to. It does it at all RPM's. I haven't got on any stretch of road long enough to see if I can feel any hunting or jerking...I am almost certain that it would. I have tried to find posts on the site and I can't find any with my symptoms.
I checked all the vacuum lines for leaks.(cut old ends off and reattached) Checked the Pressure Regulator, vacuum side for leaks. Cleaned the throttle body (also made a rubber gasket for it) Cleaned the throttle switch (removed all the carbon deposits on the points.) Checked the AFM Flap for any damage (have you checked the price on these babies? Ouch!) I am at a loss...any advice you might have would greatly be appreciated. Thanks in advance...

Damn this is spooky... (IMG:style_emoticons/default/hijacked.gif)
I have been hunting down Fat/Rich running problem on my 75 1.8 that is in a 72 body. Fixed every frkin potential problem I could find with no luck. Documented in another thread. This thread got me to thinking what I had done since getting the car in April of this year. Well damn I was carrying spare relays in the open slots in relay board from something I had read here at one time about it being a good place for spare relays. So I removed all 4 of them and left them out since I do not have Rear Window Defrosh or a working Heater. The second relay back from firewall had to be pryed with screwdriver and appears melted around the edge. Is this the FP relay spot for a 72? I start the car up and it hit 800 cold idle(has been a problem) purring. I WOT it a few times and there is no more smoke pouring out the tail pipe! I drive it to work today and it does not appear to use a drop of gas. I have been able to almost watch the needle move down constantly. Is my rich problem solved? Was it really that easy?? I will see soon enough!! RCR this wkend... Could it be the relay board was still wired up 72 style and the relay was causing some kind of shorting out?? I will leave that for those smarter than me. Sorry to ramble... (IMG:style_emoticons/default/biggrin.gif) JKP |
