Hiya, I hope all members are doing good.
Firstly, the truck idles fine, and generally drives fine. However a couple of times recently, when going to pull away (i.e. vehicle standing at idle), there has been no response when the throttle is pressed. The engine didn't die, it just didn't respond.
I am thinking this isn't fuel delivery, as it idles and otherwise operates normally. I have not got an error code, but this has happened only twice in 60 miles or so, so perhaps the faulty component has not yet generated one? But I want to sort it before it gets worse.
Anyway, my suspect is the TPS, as I am pressing the throttle but there's no subsequent response, Before I start throwing parts/$$$, it there anything else that may be a likely nuisance?
The only other issue is it VERY occasionally misfires if I have to accelerate when already doing highway speeds (to overtake, or tackle a steep hill). I am working through the likely causes (plugs/leads etc, got a new cap and rotor arm on the way). I don't believe this is related to the other issue, but thought I'd mention it in case it gives someone a lightbulb moment.
Thanks!
