1989 VOLKSWAGEN JETTA Vehicle Speed Control Problems

WHEN TEMPERATURE IS 5 DEGREES F OR LOWER (COMMON IN MINNESOTA) THROTTLE WILL STICK OPENLY. EXTREMELY DANGEROUS AT HIGHWAY SPEEDS, ESPECIALLY WHEN ICY AND RPMSAND APPROACHING REDLINE. NOT A RARE PROBLEM IN MINNESOTA, WHERE IT IS OFTEN COLD, WITH 1988 AND 1989 JETTAS (WITH THE DIGIVOX SYSTEM).TEMPORARY FIX BY DIERCK'S REPAIR (BYRON,MN 507-775-2754). VOLKSWAGEN USA CLAIMS NO KNOWLEDGE BUT DIERCK'S SEES SEVERAL EACH TIME IT GETS COLD. WHEN ENGINE IS COLD, WARM AIR FROM ENGINE IS BROUGHT INTO THE THROTTLE HOUSING, CAUSING CONDENSATION.WHEN THE ENGINE WARMS, INTAKE SWITCHES TO OUTSIDE AIR, WHICH IS VERY COLD, AND CAUSES THE WATER TO FREEZE, LEADING TO THROTTLE STICKING. TEMPORARY FIX CONSISTS OF DISCONNECTING WARM AIR INTAKE IN COLD WEATHER AND PLUGGING PORTS.HOWEVER, THIS LEADS TO SOME EXHAUST COMING OFF THE ENGINE AND INTO PASSENGER COMPARTMENT. VERY PREDICTABLE PROBLEM AND PREVENTABLE IF VOLKSWAGEN WOULD PROVIDE FIX-IT KIT. DIERCK'S REPAIR IS WILLING TO TALK ABOUT...
