Engine hunts

[sunnfish]

I have. 99 and I replaced the map maf water therm. Front O2 sensor. Now I have check engine that says to rich and the engines hunts up and down until it kills. Are there any tips I might try?

sounds like a vac leak. you can fire it up spray the vac line with carb cleaner, if the idle jumps up you found your leak area. check the fat hose off the TB to the evap that one likes to crack, as well as the t under the snout. being you changed a bunch of stuff a line could have cracked.

post the codes your getting.
