Rough idle poor acceleration hesitant new spark plugs spark plug wires coils data pressure sensor replaced need help

 

You have a misfire on #1 cylinder.... plus a lean code. Could be the #1 fuel injector... I would start there.

 

Did you have the Rough idle poor acceleration hesitant before you changed out the plugs, coils etc?

 

Yes, +1 ^^^

P0301 means #1 cylinder is misfiring

P0171 means Lean exhaust seen so computer added more fuel<<< this code comes from the Misfire

An O2 sensor only sees Oxygen in the exhaust, not fuel, Lean code means there was too much oxygen, so P0171
If a cylinder misfires then NO Oxygen was burned up like when a cylinder fires, so that oxygen is dumped into the exhaust pipe and O2 sees too much oxygen, P0171

If you don't want to waste more time and money I would do a compression test on the 4 cylinders, if #1 is lower than 2, 3 and 4 then no amount of time and money spent on the outside will help

Once a compression issue is taken off the table you can look at spark or fuel
