1987 vw cabriolet idles up and down. When you accelerate it bogs. If you come off gas pedal a little rpms pick up. Has new distributor, coil, fuel pump, plugs and wires. Also cold start vavle replaced. Sometimes starts right up other times takes 5 or 6 times. Driving me crazy. Thanks Joe

At that point, I think the best thing to do would be having the carburetor taken off, take it apart, put it in some gunk remover (Carburetor Cleaner sold in 1 gallon barrels), then wirebrush it all out, make sure all the jets are clean, buy a carburetor repair kit, and put it all back together with new seals. At how old your car is, it would probably be best for it. On the cheap side, all that needs to be done is having the carburetor's throttle accelerator pump fixed (Squirter). A shop should be able to do all this, but it's not hard, either.
