I’ve noticed a few weeks ago that on cool mornings (before this heat wave) that my MCS would struggle to turn on. I’m 10K away from my next service and I’m at about 34K. I’m thinking it may be the spark plugs. I just cleaned my CAI to eliminate that possibility.

I didn’t want to take an extra to Towson if I could help it. Does anyone have any ideas?

PS: My MODS consist of - ECU Flash + CAI + 15% pulley + JCW Exhaust

 

Try some different gas.. if you're buying from the same station all the time it could be your gas station.

 

Could be carbon buildup. Does it shudder at cold start or just not want to start?

 

Fuel pump?

 

^+1.... They've extended the warranty on the fuel pump to 100,000 mi. so take it to the dealer
