Im not sure yet...I was running about a 1/4 tank of 87 and put another 1/4 of 93 in it with no difference. Ive noticed it in the last week or two just seems flat until about 4k...In fact I accidentally hit redline hard the other day cuz the power was just not coming on like I have been used to.
. Check your air box, filter, and snorkel (rear of grille) for obstructions as it sounds akin to an induction system issue (sounds like whatever it is its before it hits the Mass Airflow Sensor)Took her out for a cruise with some other mustangs and stop light to stop light this thing felt like it had no throttle response and very soft in the lower RPMs. No idea whats up with it but it seems to be running sluggish lately. Anybody experienced this? 70 degrees low humidity felt comparable to my 2007 GT honestly..Dont really know how to take it to the dealer and say its just not as fast as it was with no codes showing....
There are zero issues running 87 and savings aren't marginal at all.
This. It sounds like it's starving for air. I cleaned my Airaid filter a couple of weeks back and it's amazing what a difference cleaning 6 months of Texas pollen out of the filter made. I had the same symptoms - just sluggish at the get go.
has nothing to do with 87, get out of here with that. seriously.
