Hey Mike, Have you had the codes pulled to see what is causing the car to go into limp mode ? It should not cost much at all to have this done. Everytime your ECU triggers a fault code it is stored in the ECU. Just have the codes pulled and the car will tell you what is wrong with it. You will save a lot of money in the long run. There is a plug on the drivers side of the car by the lower dash that a code reader has to be pluged into and it will read the stored codes and tell you what is triggering the code. You might also want to try a real good fuel system cleaner add it to a near empty tank and then fill up with preimium gas get on the highway and do some fast careful driving keeping the rpm's above 3 thousand for a while and see if this will help. These cars are prone to get carboned up and need a good fuel system cleaner added to help keep them running good. Have you cleaned the throttlebody ? These cars need to be pushed hard once in a while it cleans carbon out of the motor it will do your car good. Good luck Mike !
