1985 vw vanagon stick shift with 100000 miles water cooled. My son was getting on freeway and had the radio to loud and shifted into 3rd and flored it for god knows how long or how many miles and didnt shift into 4th, he says 1 min. But anyway after that, when driving, when you push on the gas full throtal it hesitates now. Like it has the wrong air, fule mix and has back fired. I drove it the next day and drove fine for 3 miles. Then I turned it off and went into a parts store and came out 10 min. Later and it started fouling up like I stated before. It dosent have the power it had and sputters. Any help. Please

Im not real familiar with VW's. Is that fuel injected or carb? When it runs normal, is it different than before?

It is fule injected. And yes it seems like it has less power. Now after driving it for a few miles it will only get ut to like 10, 15 mph. And will die. Kind of like its not geting any gas. But onec it starts it idle's fine and rev's normal in nutral.

Need to install a manual fuel pressure gauge to see if it is losing fuel pressure

Hey thanks. I changed the fuel filter first and that was the problem. But now I need to replace the gas tank. It is so rusted in side I had to change the filter 4 days later. So I thought I was getting out of spending 200 for a pump but no I just have a 190 bill for the gas tank. Thanks again
