Having problems with your 1990 Mercury Topaz ?

1990 MERCURY TOPAZ

\015 It will start but acts like it is running out of gas, computer code says egr or charcoal canister. Has a new fuel pump, fuel pressure regulator, map sensor, O2 sensor, canister has been eliminated along with catalytic converter, I can force it to get me down the road, but I have to put it in neutral at red lights. Throttle position sensor checks good, air bypass checks good. MPG went from 30 to about 10?\015 Posted / edited by AnonymousUser on : 27-09-2021

Answers :

Sounds like your egr valve is stuck open. check for false vacuum signal to egr valve holding it open or for a plain old bad stuck open EGR valve.
