Okay last night when I crossed over to vtec I got a cel let off it pulled over cut the car off and the cel went away but the car didn't start right away had to let it sit for a couple minute then it started and ran fine tried vtec again and no cel. Then today during normal driving i got a cel out of nowhere and the car acted like it was running out of gas and bucked a little bit.
I haven't changed anything on the car except the oil. 10w30 castrol gtx 4qts honda oil filter
