Some codes and stumbles at low throttle

RE: Some codes and stumbles at low throttle

I changed out the relay about two days ago. It seems more willing to downshift now. There is still some slight stumble under certain conditions, but driveability is somewhat improved. I think maybe a chip to improve tc lockup might be good. No more codes still.
 
RE: Some codes and stumbles at low throttle

after you mentioned the relay I swapped out my fuel pump relay for the horn relay, then cleared the codes. so far no more chek engine light, even when driving with the o/d off for a while. its only been 3 or 4 days of driving so I'll keep ya all updated.
 
RE: Some codes and stumbles at low throttle

I've been getting the low throttle stumbling still especially around 1000 rpm on slight inclines. But no codes. I am thinking it might be worn out wires from the VCRM or somewhere in the control circuit, or it might need a brand new relay, instead of a 10 year old one.
