Dealer Visit

[ZSHO]

Had appt last week at the Dealer for updated valve cover and pcv,the service advisor informs me will have to come back due to wrong part,spoke with the senior tech which is a buddy of mine and informed him that the car seems to run sluggish,he said while your here lets due an oil change and update your computer,told him the tune is loaded and he said next time you come we will update the computer,when i left the dealer noticed the radio was off and he resetted the dasboard settings,what surprised me was the car seems faster and the shiftt point are firmer,like when getting a tune for the first time,any suggestions? did have the tuner on the seat but not the 2-bar to put it back to stock.

Possibly a battery disconnect?

New oil with better viscosity may give the sensation of smoother and crisper function.

Anyone break the retaining red tab,clip that fastens the harness adapter for the sparkplug coils,recall breaking one of them a while back and had tech install a new one,possibly that caused my lack of spark to one of the plugs,he also checked on the ford computer and no codes were on.

 

[SHOdded]

Should only affect spark if the boot is not properly installed on the plug in the first place, no?

X2 on that^^^

Clip seems more of a safeguard than actually helping the seating of plug to boot. If it was an issue I'd think you'd get misfires that pull a code?
