I have a 91 chevy s10 2.8l v6, i replaced the plug wires and plugs, it was way over do. While i was replacing them i broke a couple of vacuum lines, there were only three. All three vaccum lines are very brittle. The truck ran ok with out them though so i thought no big deal. A week later on the highway the truck wouldn't get up to power, bogged severly. Now, the engine dies and sounds like a sick b-52 during take off, sometimes a lawnmower when in gear trying to move (loses all power under a load). I just replaced the manual transmission had it proffessionally rebuilt. I used the self flash test and got error code 33 (map sensor high) and error code 34 (map sensor low), I dont have a meter to mesure voltage and dont want to replace it if I don't need to. I already replaced the fuel filter, the spark plugs and wires, rotar cap and distributor cap. I also recieved error code 21 (idle switch circut open or WOT switch circut shorted) and 22 (fuel cut solenoid circuit open or grounded.
