I don't find that as a real code for that car. What are you using to retrieve that?
Thanks for quick response. I could not find fault failure 99 on my manual. It displayed only this code.. I dont know what it is. Let me describe my car problem a little more. My car can start at 500RPM ( should be 1500RPM) and shake engine. If I step on the gas, the engine will be fine, e.g. 30MPH at park position It could not go higher speed of 50 on the highway - heard noisy things under the car. I replaced plugs,wires,gas pump,filter. Next will be carnister,ignition,or throtle. Any advice?
My car has ODB1 next to cruise control. I pressed VCM button and showed this code. I removed ground battery and then again it showed the same code.
Disconnecting the battery will simply erase all stored codes. You need a professional OBD1 scan tool to read the actual stared codes to have any kind of starting point here.
