The car is a OBD1 93 passat vr6 recently did timing chains and tensioner about 10,000 ago with no timing trouble. The engine seems to be going fine untill no matter how much throttle you give it just puts along, it happened the first time on the highway. I did the spray test and the coil pack and wires do not arc, and the plugs were done when i did the chains. Something wierd is when the maf is unplugged the car runs the same as when it is plugged in. I am thinking cps or possibly the controll module. The key is that the engine will do this and then work again. Sorry for the lengthy post but I wanted to get as much of it down in one shot. Thanks in advance for any replys.
