i got a 93 f150 4.9l 5spd 4x4 126,k miles. and i have reproderd of this clicking noise by the intake and my truck having like no power. well i got off the highway and got home and poped the hood on my truck and didnt hear any clicking noise and then all of the sudden it started up. im thinking it is a bad fuel injector cause the engine is sooo loud it is kind of hard to hear. i have been running injecor cleaner in my gas every couple of months and i have done seafoam treatments. is their a way to test these? if they are bad i might just replace them all. can i put a bigger injector in the truck if they are bad?

 

well i took my mechanics stethiscope and listened to the injectors and i think it might be cylinder 3 cause i listened to the first too and listend to the open and closing as i give the truck gas. as i got to injector 3 and i heard it was closing slower than the other 2. so i think injector 3 is sticking or just worn out. i do hear a poping in my exhaust when it is idling. so im guessing it could be one.

 

hey man i just bought one of those. how does it work? im just waiting for it to ship.

 

the chip. i would not reccomend doenst work. it will wreck the sensor eventually.
