Having problems with your Cars & Trucks ?

1994 Toyota 4runner runs intermittently, no vacuum sounds as if there is a leak, all fluids topped off, truck cranks over and does start but will not stay running. Idle changes drastically until hot. Once hot idle steadies. If I try to drive truck once idle steadies it dies and the process restarts.

You should check you MAF sensor. clean your throttle body and change your spark plugs. shouldn't be anything if you say there is NO vacuum leak.would recommend searching your PCV valve for a vacuum leak
