Hard start issue

[kazi]

So just got the car back in the road and I'm having a hella time getting the car started from cool or if it's been sitting a few hours after a drive. car tends to pop and bang though intake if it takes any longer than 5-8 seconds to start which also sounds like when the starter motor starts to die off.

from warm or an hour or so after being started/driven the car normally turns first time of the key, but the starter motor tends to engage for longer than it should.

I was originally getting codes 4 coolant temp sensor, 5 couldn't find much on this but got it down to 02 sensor & 7 open/short in TPS signal circuit.

I've changed the 02 sensor, igniter & dizzy and that has cleared code 5&7

Car started a lot easier but still required the foot pumping the gas peddle for a few secounds. I'm now getting code 11 AC conditioning switch on/ IDL points in TPS off. I only get this code if I hold down the pedal and then it goes away.

Static timing and gun timing are bang on.

And ideas on how to solve this code?

Would a gubbed starter cause these issues of hard start? Starter motor seems to engage for longer than it should. i know it wouldn't cause the EML code but wondering if lack of power in the motor would cause this.

Thanks in advance
