I took this page with everybody's responses home last night. He responded by telling me this stuff: According the Chilton's, the psi is 1.3 to 2.6 for the fuel. Also, he checked the idle speed, and EGI system. No fuel injectors, electronic distributor, distributor cap is lined up properly. can go from 1st to 2nd no problem, if on freeway going from 2nd to 3rd, it'll start jerking, first he thought it was ground wire, but it was okay. So was the oil pump. Sometimes it does it when going from 3rd to 4th on the freeway, can only go up to 45 mph while in 3rd. This model uses a thermal vacuum valve, this valve activates the EGR. The thermal valve checked out ok and so did the EGR. Check valve is okay as well. has a weber carb. According to Chilton's, the fuel system is pressurized. He replaced the fuel filters a month ago. He has checked the suction in the line from pump to filter. Float and fuel level in carburator checked out okay. He's next going to check the oxygen sensor below the boot.

I believe he said there were 2 or 3.

Already did that. No luck yet. Do you or anybody on here know anything about a pressurized fuel system on the Subaru Brat? He said to ask because the Chilton manual said something about it.

Originally I posted this in Historic, but I got an update from my roommate. I had the wrong model year. The post belongs here instead. My roommate owns a 1983 Subaru Brat. It has this problem in which it goes up a grade, it'll surge and stop, surge and stop, until the motor dies. My roommate has replaced the oxygen sensor, something that starts with an E, the fuel pump, the gas tubes, the vacuum something, and some other stuff but the problem is still occuring. What can anybody do? If you need more details, let me know. I just spoke with him. He has done the following: All vacuum lines checked, replaced vacuum sensor, the EGR valve, and the fuel sensor, no problem with piston or rings, he had it tuned up a month ago, and he has already replaced the fuel filter. What else is there to check?
