Review on 🧰 ACDelco GM OE 12615873 VVT Solenoid for Variable Valve Timing by Jamal Edwards

If you're buying this you probably have a trailblazer or messenger. It means you're in trouble. Like me. Problems you don't know how to fix. This can be your problem. But be careful, if you replaced the fan clutch with something other than the Delco brand, then this is your problem. Yes, I said fan clutch. It works in the same way as the valve timing and camshaft position sensor. And it will short them out if you buy a cheap fan clutch brand. Same as mine. And mine, in turn, ruined the gearbox due to power spikes and erratic revs. So. Replace this, make sure your fan clutch is ac delco and that your VVT sensor is ac delco too. And you get your power back.
