Ok 92 z28 55,000 miles...car is using gas ,there is a strong odor of gas and it seems to be laying down off the line a touch. i checked the fuel press..40 psi and checked ohms at injectors..all 16 -17 ohms..put the stethosocpoe on the injectors and they are all clicking..could the tps be at fault at all for this?..thanks
