98 S70 evap purge valve issues

Post by buffsstuff1 »

If for some reason the evap purge line was broken somewhere between the canister and the evap purge valve, would it cause stumbling upon quick acceleration?

The car does fine at idle, does fine when the gas is slowly pressed, but when the gas is pressed quickly, it just bogs down. Any help would be greatly appreciated, thanks :P

It's much more likely the leak is in the elbow than the purge line

In general: no. EVAP hose, when broken, is not big enough to cause lean mixture. Simply b/c the diameter of these EVAP hoses are small.

Check around with a flashlight and mirror, some of these broken hoses are tough to find.
