DO U HAVE ANY ENG CODES? HOW LONG HAS IT BEEN SINCE FUEL FILTER WAS REPLACED?
no engine codes,replaced intake manafold gasket,new fuel filter,
new air filter. after repairs collant leak was fix--and engine ran great!
Then idle and acceleration got weak(mostly)still ran ok,but just a little weak----but,at times it would return to running just fine(the acceleration is very impressive)

idles rough- hot or cold engine
