Throttle response issue.
Pressure washed my engine yesterday and washed the truck as well.
After I pressure washed it, I started it up and it fired right up, no issues. I then washed the truck and left it alone until this morning.
I got a check engine light.
I thought it would go away after I put a few miles on it, but it stayed. Running AE, I got ICP out of range and IDM fault. I'm thinking I got water in/around the IDM in some way.
After I sat at Starbucks for about 30 minutes, went back out to the truck and it went away but came back during various times for the next 10-15 minutes but then went away completely.
Now, I have a slight throttle lag. I can press the accelerator down a little bit before the truck really responds, but once I get to a certain point on pressing the accelerator, the truck lights right up.
Idle also seems to be a bit low, it seems like it needs to sag a little when I come to a stop, then recover back to normal.
I'm taking it this is all unrelated, but can the accelerator have an issue like this, is it just going bad over time? No codes other than the normal ones . . .
