Question about 1985 Volkswagen Golf
After renewing timing belt and camshaft oil seal, the engine would start and stop. Sometimes it will idle without engaging the choke but at very low revs and erratically. The engine hesitates upon accelerating. Timing has been verified manually. Vacuum leaks have been checked but none found. Not sure how to verify enough supply of fuel supply to the carburettor...I am also buying a stroboscopic timing equipment to verify timing. Any kind of assistance to held diagnose or find a solution will be appreciated...

The timing could be 180 degrees out you will have to do it all over again. Bring #1 cylinder upto TDC check the distributor rotor arm that it is pointing to #1 plug wire, It is important that the cams are on the intake stroke and not on the exhaust stroke. The crank is no big deal just make sure the marks are lined up.

Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"
I have a 98 passat 4cyl turbo and my oil light and now engine light is on. Took it to checkers for a diagnosis and they couldnt read the computer. Just passed emissions 4 days ago and they had to try 3 times to read the computer. What are some reasons this might be going on?

check and clean your air idle control servo motor usualy located on or right next to the throutle body. check your map sensor also. the iac. is bad about getting gummed up and sticking closed or wide open, check that your air breather tubing is hooked up good no cracks or tears. could be messing with your mas air flow sensor which plays a major role in air fuel mixture and computer controled temp sensor could be failing it acts like an automatic choke. a scanner could help you out alot if you can have a local shop scan it.
