Engine shaking, Please help - Toyota Nation Forum : Toyota Car and Truck Forums

My car is 98 camry LE. It has no problem at all when I drive it locally. Last time, after I drove at a speed of 75mph on highway for about 5 minutes, the engine became shaking greatly when I was waiting for the traffic light. The engine speed jumped back and forth between 0 and 1000rpm. After a while the engine went dead. I strated it, same situation. After several minutes, I started it again. It became normal. I drove back at a lower speed. I had met this situation before. I asked the dealer to check the problem. They told me to replace spark plugs. I did it two months ago, but it seems that did not solve this problem. I am guessing something wrong with my EGR system. Could anyone give me some advice? I really appreciate your help.

Yeah, could be a vacuum or EGR valve leak. Start by checking all the lines for cracks and stuff.

I'm having problems with mine, but I think mines more timing than anything else.

In P and N, its ok...but in a drive gear at when i come to a stop, the idle drops down really low and then jumps back up again to normal...!!! weird.

But if yours is fluctuating..test ur EGR or vacuum systems.
