Low mpg 3.4 1994
Hi
I have a 3.4 94 camaro its got 110k miles on it there are a couple of issues I have had since I got it that seems impossible to solve for me.
1-engine vibration can be felt at Idle(replaced the eng mount already didn't work).
2-low mpg
I have Replaced injectors,plugs,wires,mudules,fuel filter,IAC,TPS,o2 sensors,map sensor,temp sensor,oil and filter,but no luck I have checked the fuel pressure and thats fine.rpm is stable with no fluctuations at idle small hesitation when accelerating slowly but on heavy acc the car is just fine.
I have replaced everything except air temp sensor and fuel pump and diaphragm. All the parts are gm genuine except for injectors off ebay.
Any ideas what to do next?
