When truck's spark plugs need changed, what would be the symptoms?
My truck is running like $@$*, takes many cranks before it starts, and when given gas it wants to die... I pulled throttle cable while under hood and could hear my aftermarket k and n air intake make some weird pressured air releasing like sound. But truck is due for a tune up.. Oil, filters, plugs... But,i just had a shop put,in a new fuel pump and a few days later it started having issues when I hit the pedal 3/4ths the way down and hit higher rpms it was like Getting stuck at 4 grand and making the transmission confused and making it shift weird but ran smooth and shifted smooth when you did it with pedal like halfway down. Shifted at around 3 grand each gear
... And it's literally,gotten worse every day and now was bogging down when just trying to leave the driveway.... Could anyone give me any insight on this issues(s) that I have going on? Thanks much
Is this a good question?
