I had these 4 codes show up car went into reduced power, was able to clear the codes and go on but now no dice. Changed TB and no luck, then pedal and no luck. I two wires at the pedal that have 5 volts unblocked but when attached voltage was no longer the same. I cant find any wiring diagrams so that I can chase it back. Found one set of grounds below the air cleaner on the block. It must be a bad connection but not sure where to start. Any help would be awesome.
Thanks Rick

on the side of the tb is a part #, you need the same one or it wont work right. seen it happen to another guy here who did a engine swap and figured he'd just use the tb on the new engine, but he ended up having to use the old one off the blown engine.

So I seen different numbers on each one, there was a laser etched set of numbers. Do you know what i'm looking for?
Thanks Rick

FIXED Bad ground from the pedal at the TB. It was backed out of the connector a bit. Always had an occasional issue with starting. Cheap repair if you don't count the headache and hair pulling. Thanks for all the help.
Thanks Rick

Hey hello Mtbuicknut. I am having the same issue. when you said "it was backed out of the connector a bit" are talking about the connector at the TB or the connector at the pedal?
I did not replace anything yet cause from all the forum post I have read, no one has fixed there problem by replacing the TB or the throttle pedal assembly so before spending money on part I did cleaned the TB witch was very dirty. I erased the code and it came back 3 days later. Then I check the wire at the connectors witch look find but I cleaned the connector anyway.
Maybe I did not check the wiring deep enough so maybe there is a weak spot in the harness so why I am very interested to know where your bad ground was exactly please.
Thanks
Rick

I have been thinking correct me if I am wrong please. If the pedal throttle assembly was misreading or malfunctioning will it still be able to make the passing gear get on? I did some test when driving with the code "ON" and the passing gear get on as usual and the throttle seems pretty accurate when raving the car on neutral which make me think it is the throttle body or the electrical around it... chasing a bad wire in the harness is pain in the ass duty...Originally Posted by rickwr88
