Hi everyone,
I’ve gotten the P1128 code twice. The first time I got the code, I only had partially cleaned the TB and the truck went into limp mode after 90 miles. So then, I completely removed and cleaned the TB and the truck didn’t go into limp mode after 90 miles. However, today after 180 miles or so since cleaning the TB the LC threw a check engine light. I got the code checked out by Autozone and their scanner said it’s code P1128 again. I thought I had fixed the issue and I didn’t need to replace my entire Throttle Body. Anybody have any other suggestions to fix this problem. My LC has 132,000 miles.
