- 1999 explorer
hi,i'm devildog13,and could use some help. i have a '99 explorer,eddie bauer,with the 4.0 v-6,sohc. it starts,idles fine,but even going up the slightest hill,the engine bucks,lurches,or whatever it's called. i have replaced the upper,and lower intake manifold gaskets,iac valve,throttle position sensor,plugs,and wires. i also replaced the maf sensor,but could not find a complete unit,(sensor & housing). it says in my manual to replace the maf sensor as a complete unit. any toughts on what to try next would be sure appreciated.thanks!
