I have a 01 that has just had another rebuilt pump put on it. It has developed a very random jerking like the pump is shutting on and off fast. It may do it a bunch and then not do it for a few days. It had one code on tps and I put a new one on but it didn't change a thing. My mechanic has been driving it for several days and it did it once and never again for him. I've about had it with these vp pumps, four in the last 6 months or so.
Has anyone ever run into this problem. I'm thinking it's time to put the p-pump on it I should have put on after the first vp went south!
