no tach = full throttle capability
i have a '88 non-turbo. i get little to no acceleration when i go full throttle. i'm assuming it's a vac leak and/or ignition timing. BUT, maybe 1 out of 40 or so start-ups, my tachometer stops working and my car accelerates just fine when going full-throttle with no hesitation or any lack of power. any other time i start-up my car, the tach will work again and i'm back to horrible acceleration. what could cause this to happen at random?

^^^ I agree with FC3Sdrift. The TPS could be bad, and it's fairly easy to check so you should do it anyway, but I suspect there's trouble with the trailing coil. OH, maybe your timing is off AND you're having trailing coil problems. See, your trailing coil is what drives the tach. If the coil stops firing your tach stops working. If your timing is so far off it may actually run better without the trailing coil firing... So there's a theory. Good luck.
