Hi Everyone,
It's been a long time since my last post. I have a 92 Cab and am in the process of restoring it back to its original glory.
Let me state my problem.. Starts and runs good. Under no load, seems to rev decent but when you go to drive it, it seems like there isn't much power.. when I press on the gas pedal I get induction noise but no real power. Also, when I reach about 4300 to 4500 I get engine ping and have to back off the pedal. After setting the timing and very sure that mechanically things are ok. I'm not so confident that the Solenoid is doing its job. Its almost as if the car isn't retarding the timeing as I increase RPM's and if I understand it correctly, it should begin to retard timing at 4500 rpm to allow the engine more power to achieve the higher rpms.
I'm looking for any advice from this point forward. I'm thinking it could be the solendoid or it could be the ECU. Has anyone else had this issue and if so what did you do to fix it?
Here is a little more background on what i've done to the car. Since my last post i've completely rebuilt the engine and clutch system. While everything was apart, I replaced things like water pumpt etc. So i get it all back together and I painstakenly put the engine in time... followed insturctions to a "t". I was hoping that my original problem would be taken care of and that was lots of induction noise but no power. After all of this, i'm down to wondering if my variocam system is actually working. I've looked at just about everything regarding that system. The cams look good, chain and pads. I've added air to the system while timing and I can see the piston advance and move the cams. I applied 12V to the variocam solenoid and can hear it click but i'm not sure its actually working.
I appreciate any help
