Here are the common problems:
leak between the MAF and the throttle body;
leak in the PCV system, especially the hose elbow;
leaking intake manifold gaskets;
any other vacuum leak;
"lazy" oxygen sensors (the front ones).
Is this what these’s code’s mean?
Thanks

There are 4 codes generated. Each one leads to a bad MAF sensor or a vacuum leak. I have cleaned the MAF sensor and also listened for a vacuum leak but have heard nothing out of the ordinary. Any suggestions?

i've posted a question on here before, about how our 1988 ford taurus dies everytime we stop at stop signs or red lights. or if we're in a parking lot, and we hit reverse to back out, it will die then too. but it WILL drive fine on freeways, side streets, etc. it only cuts out and dies when in reverse, or at a stop while in drive. its an automatic. i replaced the brake booster, and the problem is still there. i've looked for a vacuum leak, but can't seem to find a leak anywhere.. i'm getting very aggravated at this. can anyone help me?
