I've got a 93 SHO automatic with 165K on it... this is my second SHO I also had a first year 89 for a while.
The 93 has been in the shop more times than I want to count and all with no resolve to the problem... which is: occasionally the engine feels like it is missing badly. Feels like it's not hitting on all 6 cylinders. If any of you know what a fouled plug feels like then you have a good idea as to what mine is doing. This occurs from a standing start and normally clears up when I accelerate more aggressively. Sluggish and then around 3,400 RPM it’s back to the good ole SHO...
This happens when it' hot outside or when it's warm with high humidity...
I've changed, the coil pack, new plug wires (expensive item) new plugs... all to no avail.
Anyone got any ideas???
Oh yea, the check engine light is on most fo the time but I've been told it's due to carbon build up in the intake... they've tried to clean it several times and it seems that within a week of cleaning... the lights back on. I don't believe this has anything to do with the sluggish acceleration.
