Okay guys or gals..i know this subject has been beat to death but i just have to ask...ok 92 z 5.7 liter 55,000 miles on car. Fuel milage is suffering and a STRONG odor of fuel...and car seems to lay down a bit from a dead stop when i romp on it..I just checked fuel pressure at the rail and it was 40 psi...so i guess the reg is good..could i be looking at some bad injectors.. ...or something else all together? only mods are as follows...KN filters..hypercrap chip..borla cat back..airfoil..and 160 deg stat...thats it...any help is appreciated thank you.

 

ok..checked ohms at injectors..all 8 reading between 16 and 17 ohms...used stethoscope and all injectors are clicking...narrowing it down.. ..tps check coming soon.

 

when was last time you changed plugs and wires
