Hi guys. I have a '95 SC, auto tranny with all the extras (coy miller, double intercooler etc etc.) All was well until one day...
Sypmtoms: If I hold the gas steady while in park so as to keep the idle at we'll say 2000 rpm, it will hold there for maybe 20 seconds then the idle will drop down to 1500ish and back up to 2000. It takes maybe 2 seconds for it to drop and come back up. My foot and the gas pedal don't move at all during this.
Where this is bothersome: I can be on cruise control at 65 and I'll hear a "cachunk" or maybe feel it more than hear it, seems to come from the rear and I'll lose power for a second before it fixes itself and gets back to 65.
Most often noticed during fairly hard acceleration. I live off an in-town highway so I often go from a stop to 50mph and I don't slouch on the acceleration (I'm not racing it, just not granying it). I will, almost without fail, have some hesitation somewhere in there before I reach 50. When I push on the gas of a coy miller Stage 2, or ANY other SC for that matter, I want the thing to move. This hesitation is quite annoying so if you guys have any ideas or easy checks, let me know. I don't have an OBD2 checker so I don't have any codes for you yet. We'll see if it comes to takeing her to a shop.
Thanks in advance,
Nate
