I just had a trip to Oregon about 1k miles round trip. Just as I got back in town I had my cruise control on and was doing about 65mph and started to go up a hill and I noticed when it went from 1500rpm to 3000pm it was pulsing like it wanted to go faster but it wouldn't like a miss fire. Then I noticed the check engine light blinking. So I turned cruise control off and brought it down to 65mph and about 1800rpm and the blinking check engine light went off.. Then I wot to see if it went away and it did the same thing. Check engine light started blinking... I found a little info saying that when the check engine light blinks that means its a miss fire. So I took it to auto zone and had no codes.. So I then pulled the maf and cleaned it. Still no change..So then I pulled the plugs which look original and changed them along with new wires. Still no change! So whats my next step? Coil packs?? Is their a way to test them? Anyone have this problem?
