Running an engine with no exhaust back pressure can burn up your exhaust valves ... donno if that's the problem but if the valves got distorted they could have damaged the seats when restarting ~~~ may be something simple so valves would be the last thing I would check... good luck


Begin with the easy things. Pull out the ohm meter and begin checking spark plug wires, plugs, coil, IACV, etc. You may also want to check the fuel pump pressure. As tom (above) stated, running an engine with no back pressure from a muffler is not the thing to do.

1 out of 1 people think this is helpful.

just replaced the spark plugs the IACV looked fine so did the plugs and it still doing the same thing it was doing before idling ruff everytime I put it in gear it does a rump like it wants to move


sprayed brake cleaner on my MAS and still doing the same thing I sprayed carburetor cleaner in the intake still doing the same thing don't know what else to do....... I even put sea foam in the oil and gas and still puttering and not enough power going on......


found the problem it was just spark plug wires....
