Hey guys I did the little test for the check engine light and got something wrong with the map sensor, My gas milage is horrable and i checked out the little black line that goes from the back of the manifold( i believe the grey thing on top of the engine is the manifold) to under the MAP sensor, Im guessing this is the vacume line and it has a break in it. Could this be the problem, also another wire that goes from the manifold into this like little Top looking thing and then branches out from there to 2 wires. Well one of the lines completely broke off while i was taking out my distributor, it was old and just snapped in half anyone know what this is and if it could be part of the problem too.

also another question I changed my distributor and rotor and the wires the other day but didnt have the proper socket for my plugs. Well my car was running fine and today i changed all my plugs except one. The #1 cylinder i believe because there is so much crap around it i cant get to it. Well i checked how it ran after doing all of the plugs on the right side ( looking in the engine from the front) and the car sounded fine. Well after i finished the 2 on the left side now the car sounds kind of jumpy. I tried getting to the 3rd plug by taking out the EGR but i have a 92 and after going too far i decided this isnt a good idea. I heard they are electronic and that scares me. SO with the rough riding and it feels like it sometimes skips right in the middle and have a brief second of no acceleration, what could this be
Thankyou much
Mitchell
