![]() ![]() Sometimes the MAP hose gets lost or gets soft. It is supposed to be a hard plastic hose so it can't get sucked shut by the vacuum that our motors produce. Sometimes oil blow-by builds up and blocks the vacuum from the MAP sensor, and sometimes people use a soft rubber hose as a replacement and it gets sucked shut. I now check my hose and MAP every month or two for oil build up. Just to keep a clean signal. Oh, forgot this. If a back fire upon start up happens the MAP hose usually gets blown off and your symptoms are a result...the bad or rough running. The most common reason for the back fire is improper key work upon start up. Remedy is just to hold the key over to start until the motor actually runs. The Cam sensor clean up I did is as follows. Spray contact cleaner in the female ends, and used a pencil eraser on the male ends, and then a dab of di-electric grease just to keep that rubber gasket and the terminals from having moisture get to them. I can't say as it's a permanent fix, but every so often I try to devote some time to going over all my connectors and ground points just to be sure. ![]() ![]() Tom
