My Chevy cranks and starts. My question is what would increase my engines economy more; replacing all four O2 sensors, OR replacing the IAC valve and the throttle position sensor? Thank you for content and thoughts.
since this is a carburated car i dont think we can still increase fuel economy..good spark plug that gives a good spark can make ur car run better good fuel too and check for vacuum leak those probably can help for good fuel consumption
@@asianmechanicguy6483 Thank you for your answer. My Chevrolet van is a 2001, so it is fuel injected (5.7 L). Recently, I replaced the spark plugs with Denso Iridium TT (4713) spark plugs and an air filter. That’s why I wanted your advice on the next parts to replace to improve the van’s fuel economy. I thank you for your shared knowledge and shared experience. So, would new Oxygen sensors or a new IAC (Idle Air Control) valve and TPS(Throttle Position Sensor) improve the fuel economy of my van? Thank you and have a good day at work.
