Well have replaced most of the sensors & switches. Put in a new thermotime and cold start valve yesterday, air regulator the other day - still had to let it idle to warm up for 10 minutes before I could hit throttle without afm popping and car dying out. **** - now what. Reset the idle and timing tonight and it runs fine while warmed up. I have a Calf. car but replace the afm with a federal used one which seems to be functioning ok. Running out of things to try. Any more ideas ?
Car definitely has a mind of its own. I do have a fsm so can refer to it if anyone has other ideas.
Thanks for any input.

Don't think this has anything to do with it, but CA cars have the altitude switch under the driver side dash....if it malfunctions things may get wacky, but I don't think it's that severe. It's easy to bypass/disconnect.

Mine is doing the same thing. I"m getting really tired of it and considering driving the car into SF Bay! I"ve replaced practically every part in FI system, done all the FSM and have it runnning ok when warm, but cold it sucks. This is a new problem...I just replaced the AFM with a junkyard one that checked out ok on the resist. measurements. Before the AFM, it idled rough cold and warm and failed smog. Still have to see if it will pass smog. I just feel like I'm chasing my tail on these problems and its frustrating. Just had to vent.

Guys, I had kindof the same trouble with my '77. Had to replace alot of blown relays and sensors to get it to go, using the FSM as a guide. The real sticker though was the FI relay, up under the driver's side dash. That was causing the most trouble. Just thought I'd mention it, and give a little simpathy because I too one thought of driving my car into a large body of water. Good luck, LeeZ

it may be the timing but check for vacuum leaks. i had a big leak in the distributor
advance pot. i was really digging for things that caused a vacuum leak. i even
sanded the underside of the oil cap so it seated good and took a pair of vice
grips to the oil dipstick tube to close it up a little for a better fit
im up in santa rosa if u want i could take a look at it
