I have a Toyota Camry 2000 model. Over the past 3 years, I would of spent about $3000 on it for services, transmission services, O2 sensors...... I must admit, I have had my car for 11 years, and haven't had to spend much money on her until now. The problem.... I feel that when my car gets hot, she starts to jump around and I feel like she is just going to conck out. The revs needle jumps about, like an erratic idle. The temp needle will go about half way, then it will drop to cold, then it will maybe go back to half way. It gets pretty scary driving along the highway. Also my car doesn't feel like a V6, it feels like there is NO power behind it. Like I said, I have had services, transmission services, I even spent a fortune on the O2 sensors (thinking this would fix the problem). If someone could help, or even tell me what I should be looking for to tell my mechanic, I would be so greatful!!!
