ACDelco 213-928 GM Original Equipment Multi-Purpose Temperature Sensor

Identical to OEM for 1991 Chevy 1500 Silverado 350 in fit and finish. For some time truck has been hard to start. Sometimes the gas pedal had to be floored to get started, then I'd have to jack the pedal until the engine smoothed out. More recently it began idling fast, but otherwise running ok. Finally, a week or so back, after it warmed up, it would die as soon as I gave it any gas. By cranking while flooring the gas pedal, I could restart it fairly readily, but it would exhaust a fog (un-burned gasoline). Clearly truck was being flooded (this tbi truck engine evidently is among those designed to clear intake by cutting fuel delivery when pedal is floored, which is why it would start with pedal to the metal). Had to disable one of the two injectors (removed one injector connector) to keep truck running long enough to be able to move it out of driveway (running on one injector worked, whereas on two the engine would die, indicating too much fuel was being injected). If you have good spark at the plugs, timing is right, compression is good, fuel is being delivered, and air filter is reasonably clean (and you otherwise have good cranking) - this is most likely your no-start/hard-start/flooring-required-to-restart issue. Easy fix. Be careful when removing the connector-if as old as mine, the catch is brittle. Loosen old CTS until it can be turned by hand, then quickly swap with new. If engine is cold, loss of coolant need be no more than nominal (relieve pressure first if engine is warm). Proper tool is 19mm deep 6 pt socket, but 3//4 6 pt works fine. With this new CTS, my Silverado is running like new, and I expect I will get much improved fuel economy with this new ACDelco 213-928 CTS.

Changed the temp gauge reading, worked perfectly
