Im 18, new to Contour.org. I just bought a midnight red 1995 ford contour se 2.5 v6 5 speed with 70,000 miles on it. I put on a k&n air filter, k&n oil filter, and started using synthetic oil. I have had the car for 5 days and the check engine light has been coming for about 5 minutes at a time then it shuts off (just before i get it to autozone to have the diagnostics run) haha. Anyway what could be causing this? I had autozone do the diagnostic it anyway and these three codes came up! code #1. 117 Engine coolant temperature sensor signal voltage is to low. code#2. 157 Mass Airflow senser signal is to low. code#3. 172 Heated exhaust sensor voltage signal indicates "rich". Any help with this would be more than helpfull! thanks, dave.

A bad coolant sensor could also be causing the 172 code. The 157 could be caused by oil from your K&N. I would replace the coolant sensor first(it's cheap)and I would also clean the MAF sensor with some contact cleaner(BE CAREFUL!). Get the codes erased and see what happens from there.

I'd pull that K&N air filter when you clean the MAF. After you get it squared away so that the CEL stays off, then try the K&N again (if you really want to

Yeah Dave, don't over oil those K&N's they'll gunk up the MAF and throw a code.

Dave - Another thing you should know: You don't need to go to AutoZone to dump codes on a '95 ('96 and later use OBDII, which requires a scanner). It's easy: You only need a paper clip and a few minutes. Learn more here: http://www.dalidesign.com/hbook/eectest.html
