    Default 95 cobra running rough

    i have a buddy who has a stock 95 cobra with just basic bolt ons. he recently took the intake and intake manifold off to clean out carbon build up out. he put it back together with all new gaskets. he is having a problem with the car idling and when you rev it up it hestitates for a few moments then when you let off the throttle it finally revs and busts up really bad. he has sprayed starter fluid all over the intake to see if the car idles different for a change in idle but no luck. the distributor was not taken off so we dont think its a timing prob. so any inputs would be appreciated thanks guys

    check the PCV valve, and the screen under it. ive seen them clog up and make a 5.0 run like crap. also, unplug the MAF, and see if its better, run it around the block unplugged. if it gets better, may need a MAF, pull it out and check for contanimation on the MAF sensor itself

    Having same problem with my 95 gt im into valve guides now to see if maybe thats it. When u take the oil fill cap off does it suck ur hand down?
