Hi, Checking in with the gurus. I have a '90 Golf (gas engine, 8 valve) that's been exhibiting short bouts of faltering on acceleration most times when going uphill. The engine doesn't cut out entirely and continues running, but power is severely reduced so the car essentially coasts for up to 1/2 second. Not too long, then the engine returns to normal power and the car continues to run fine again. The faltering won't appear again for weeks or months. But today, it was pretty bad and I moving onto the main road from an alley and was left exposed without any acceleration with oncoming traffic bearing down. After faltering for what felt like a full second, the engine came back to full power. I'm thinking the transfer fuel pump. I believe it's the original at almost 19 years old with 216,000 km on it. Is that a logical place to start? The main pump isn't buzzing so I didn't think it was starved for fuel. If it was the fuel pump relay or an electrical problem, I'm guessing the engine would just quit. Other than the infrequent faltering, the engine runs fine.
thanks.
