Can deleting the screen in the MAF cause the service engine soon light to come on?. I recently did this being very careful not to touch any of the wires. I then took my car to my mechanic to get a new speedo cable and told him to run a diagnostic on it because the light comes on all the time and he said that the code read that the MAF was messed up not giving it the right fuel/air ratio but he said he was pretty sure that it was an electrical problem with it and i know he did not take the intake apart to see that i cut out the screens. So i was wondering if this increase in cfm could cause and error, or if he was right and i need a new MAF

 

Its a distinct possibility. What code?

 

He did not tell me and I was too involved in looking/talking about his blown 502 chevelle to remember to ask sorry.

 

That, and how does the car run? Hesitation? temperamental?

 

As long as you didn't disturb the wires inside, then no...Lack of screens alone won't cause the SES light to come on. I don't have screens. Haven't for 3 years now....No SES light.

You could get the code yourself at home, then tell us what it is.
