lost power answer:
lost power can be many things.
the valve lash set wrong, (it was) and hot the gaps go to zero and the valve fails to close and the compression drops and power drops. all normal for bad service. (this burns valves to a crisp , BTW)
if compression is good hot.
then a melted CAT? if power returns cold , the CAT is not melted, once melted inside, it kills power full time and can get so bad car will never start again.
the CAT can continue to melt running with HUGE RICH fuel mixtures.
next is limphome, if the ECU drops to limphome , the power is cut greatly, but with a dead CEL lamp , how would you learn this vital fact?
Limphome likes to melt CATS too... BTW.
bad spark, if the spark degrades in any way, you lose power. (do a 60,000 mile full tune up now)
last is bad fueling. and is always last to check. if the injection rates are too much or too little, the power can drop. (this takes careful diagnostic testing)
and last but not least here is my no/low buck solutions page.
