Surging is usually a fuel problem , check the accelerator is opening the throttle smoothly , loook for any signs of wear or holes in the air and vacuum lines , remove the air filter and see if it improves things , if all ok i'd get the timing checked , when was the last time the vehicle had a service ?

Testimonial: "had plugs and wires replaced 3 days ago. up till then my husband had it and did not have any maintenance done on it at all! Have reclaimed it since then, now trying to get it back in the running shape it was in. It started as soon as mechanic put new plugs and wires in and new battery but runs for a about 20 seconds and starts to die at which time the car starts surging and idling up and down until it finally shuts off. It has a carb fuel injected."

Sounds like the battery is weak or the alternator isn't providing enough amps to keep the engine running and power the lights at the same time.

Testimonial: "thanks , it sounds logical. Should I replace the battery? The guy who owned it before me just replaced the alternator."

SOURCE: 1988 cadillac sadan deville. i have replaced havc programer.

GM products with digital climate control used a temopature sensor module which is located under the hood in the heater box. They are known to fail. It souns like your issue lies there. It is sort of triangular in shape and has a single electrical plug with 7 or so wires in it. (I ran a slvage yard for years and sold a ton of these!) There are a series of #'s like a factory I.D./part # that I used to identify and interchange with. I don't know if there has been a generic replacement released over the years. Hope this helps!

try checking the coil for leaks. if it looks discolored anywhere on the coils then it's leaking. i had the same problem with mine. sounds like the same thing mine was doing untill i replaced the coil. could also be the drive gear for the distributor to but highly unlikely
