Hey all, Ok, I have been plugging away on my first sc400 thanks to all your help the steering wheel moves up and down in and out, the steering has no more play in it, found the water leaks and repaired. Car was running good and after a while started to run a little rough like it was missing at low speed, higher revs it ran great, changed spark plugs, cleaned the caps and rotors (ordered new ones) Started the car before I put the intake tube back on and the engine light came on, turned the car off, pulled the battery, put the tube back on and now it runs like it has half power. Any ideas? I tried to pull the ECU fuse by the kick panel ( think it was in position 13) but it didn't help, I read about changing the fuel filter, may look at that next and currently have the battery pulled to reset. Any help or ideas would be greatly appreciated, Thanks AGAIN!
