It sounds like an a/c compressor issue.Try unpluging a/c compressor under the hood and see if this helps the problem.If so I would have the compressor looked at for a seizing problem.

I have s 79 shovelhead flh just put new points set timing run down the road t about 10 miles it just boggs down and died after 4 or 5 kicks it will fire up rev 4 or 5 times then it dies what up


Hi,becouse you have just set the timing that seems the place to start,I would recheck,if after rechecking it still happens,what I would do is buy one of the sparkplug lights that gose in between the sparkplug and ht-lead then if it stops again you can see if its a electrical problem or fuel problem,if it is electricle problem then and no spark at points check coil isant bracking down.
Hope this helped a bit,all the best hope you sort it.

Engine revs in park


This is called hunting. Can be caused by a bad mass air flow sensor. Could also be a sticking idle air control valve.

1988 cutlass ciera boggs down when i accelerate


Hello! You have symptoms that point to incorrect fuel pressure.
First have the fuel pressure tested as follows; #1...engine running at idle: 13- 20 psi. #2...key on engine off: 23-30 psi. If pressure is incorrect change the fuel pump.

Does the engine "surge" at idle? If so, check the "fuel injection pressure regulator idle air control valve". Apply a vacuum to it; If fuel flows it is not the problem.

I recently acquired a 1993 Buick Park Avenue. The motor that makes the antenna go up and down runs continually but the antenna does not move. It runs my battery down and I have to get jumped off, I have...


Look in the trun k on the ant side and pull back the the felt and you will see where it connects and disconnects. You have a broken antenna lead. At the bottom of all electronic antennas is a plastic lead that fits in the motor to wind the antenna up or down.The motor is still good you only need to replace the stem. Good luck.
