hi, could really use some insight. i have a 94 idi turbo that has loss of power or a miss @ 2000 rpm on up. when this started the idle also elevated. I have checked for leaks air and fuel and can not find any. idle is constantly higher than normal all the time since this started. any help would be greatly appreciated. thanks

 

Air iintrusion , start with swapping out the fuel filter ( BF1222) use as a cross reference @ any parts store... wix has a filter that will fit and they dont have a spin on bowl on the bottom ..
