Hello all,
I have Impala LT 3.6 liter with 100K miles, last few months im feeling that when im driving the car, somehwere between 1300-1500 RPM the car choke until it it reach above 1500 RPM, then everything is fine, same issue happens when gear in neutral.
took it to a mechanic, using a computer- no issues register ,things seems fine but still...
another mechanic thinks its the coil on the cylinders and saying I need to replace them all.
Is it possible its something to do with the gas pump pressure ?
what is the parameters I need to check in a computer if I get ODB scanner to find why between 1300-1500 its not working properly ?
Thank you

Monitor the fuel line pressure with a mechanical gauge in that rpm range.
You can check the coils and see if they work fine or not before replacing.
