2000 Dodge throttle probelm?
 

I have a 2000 dodge 2500, I just put a new APPS on and notice the same day that some times when im drivin and have the trottle constant that all of a sudden its like i take my foot off the pedal and goes back to idle even when my throttle is at 50%. Ill have to pump my pedal a couple of times to get it to read again and then it does fine till it happens again. Does anyone have any ideas?

When mine went out on my 01 it just went into limp home mode. once I cycled the key it would work normal. When I installed the new APPS. It went back to working normal. Not sure why yours would do that. Does all your throttle linkage look normal. Where did you buy the APPS. I used one from NAPA.

all the linkages look good, I got the sensor from autozone cause I needed it that day and they where the only ones who had it. I dont know if this has anything to do with it but I have multiple codes involving my turbo. The only reason I changes my apps is cause it was doing the inconsistant trans shift back and forth and so on, the new apps fixed that but now i have this issue

Thats a new one to me. Not sure what other sensor would cause that problem. I assume you checked the codes by cycling the key three times. what codes are set.

I dont remember what the codes are but everyone of them deals with the turbocharger. I even hooked a scanner up and pulled codes. ill check codes again to get the number.

Check for error codes for sure and report back the P number. I've got a whole list of error codes and diagnostics for you to run.



Also another find is checking for AC noise from the alternator. Use a high quality DVM and check both DC and AC voltage of the driver side battery while the engine is running. DC should be 13.5 to 14.5 typically and the AC should be no higher than 0.1 if so you might have bad diodes in the alternator.
