OK I cant find my old post so sorry for starting a new one.. OK heres whats it doing now.. I can go 150 miles with no check engine light and no codes. But when I floor it c.e comes on and goes off read the codes and its 176 and 172 both O2 are lean. Its hissetent when idleing but im getting good gas milage. 340 highway miles per full tank. And earlyer when I put it in reverse it wanted to die. I replaced the IMRC solenoid and the 551 went away but now it ticks.I also just done a tune up and replaced the fuel filter.. Any suggestions please? Could my o2's be bad? or 1 of them?

Both O2's showing lean is usually indicative of a true lean condition. If it only seems to be happening at full throttle, I would wonder if you have a vacuum leak that only appears when your secondaries are open.

What exactly did your "tune up" consist of?

new plug wires,plugs,new fuel filter. Do you think that I didnt gap a plug the right way?

or a bad IMRC solenoid because it does make the engine tick when its pluged up.. Its not a new one I got it used.
