Driving my contour for the first time in awhile today, And when I approached a stop sign, the engine sounded very weak, (Guessing around 400-500 RPM - I dont have a tach) this is only when the engine is warm. When the engine is cold, runs perfect. Recently changed MAF (think that was a waste of money...

) Checked timing recently, think its better though... before I hadta give my car some gas to start it, now I dont. Sounds like a low RPM rate when engine is in P, but alright. Any suggestions?
