Question about 1999 Volkswagen Jetta
Did you not go for a drive with a scanner on it & look
at the data when it acts up ?
Did you smoke test the entire vehicle evap,exhaust,intake,
etc for vacuum leaks ?
What about fuel pressure on the road test ?

It could be. The car seems to be flooding its self as though you are driving on the choke all the time. Replace the air filter if dirty and clean all the breather pipes. Also check the accelerator cable is not snagged and is adjusted correctly.

Sounds like your alternator is starting to seize up. Remove the belt and spin the pulley by hand. If you hear a light grinding sound or the pulley is stiff then the alternators bearings are worn. Take the alternator to an electrical repair shop for rebuilding. I usually pay around $50 as opposed to $100 or more from a parts store. Look up auto electrical repair in your Yellow pages. Older VW's are known for starter and alternator failures so finding a cheaper source for parts should help you save some money.

engine is pinking,predetonation of fuel or the fuel mixture is weak which can be caused by a vacumn leak on the inlet manifold ,such as the take off for the servo ,or the manifold bolts loose.Also the timing is set wrong which could be a fault with sensor or the sensor drive ring .Without the car in front of me i cannot really diagnose a fault like this ,either get the VW mechanic to have a look and if he thinks its electronic then take it to VW

I would start with this: if its only happening when the engine is getting wet get a hair spray bottle, or any bottle and spray water on the engine when it is running to get it to act up. A blinking check engine light means you have a misfire, it most likely has something to do with your ignition.
The two most common things ive see when ive performed this test, was spark plug wire, or one of the coils. What you will be looking for is to see if the spark is arcing from one thing to another, like a wire, coil, something. I would start their, that is the quickest and easiest step to see you have a arcing spark.
