I have a 97 Tracker with 1.6L 16V that suddenly lost power. It has set no codes, I have had it on 3 different scanners nothing out of the ordinary. I have checked the spark plugs run a compression test, it has no miss, when you first start it it won't go until it warms up some. Cleaned the mass air flow sensor, new air filter, fuel filter, checked timing, checked for vacum leaks since fuel economy has gone from 25 mpg to 15mpg. Nothing has helped.
Has anyone had this happen to them? Any other ideas on what to look for? I know a lot of techs and used to be one myself for a long time, none of the ideas has panned out.
Any help would be appreciated.
