Vacuum hose
I am having problems again with my 97 GT. The RPMs drop and go up and it will run rough especially at first. The scan says this could be one problem. I picked up a MAF sensor at a junkyard and the code comes on when the MAF is disconnected or connected. I also feel like I am not having acceleration or stopping power as I did before, one mechanic a while back said it could be a loose vacuum hose connection, any idea where this would be? Thanks in advance for the advice or help.

Re: Vacuum hose
That sucks. I had a cracked hose and it kept shooting off my check engine light saying my EGR valve was bad. It was the plastic hose right under the S/C'er pulley. I'd check any plastic hoses first because they're cheap pieces of crap that crack easily.

Re: Vacuum hose
If stopping power decreased, check that huge vacuum hose that goes from the UIM to the brak booster.
