4500 Rev Limiter
 

Hi guys, I have a 93 FD, I recently cleaned my engine with the ams engine cleaner I purchased from Atkins Rotary, So I cleaned the engine the way the website told me too, and the car wouldnt crank, so I jump started it and it worked, Alot of smoke came out as expected but when I took it out to drive the car wouldnt let me hit over 4500 rpms, I just installed new tts, and I cant figure out the problem, and suggestions?

plugs may be fouled.
