ph1 172 poor/low idle, sometimes cuts out

[iamdaryl]

Before I decide to send the car to car heaven I would like to try and fix this real annoying problem.

I start the car and its fine, revs around 1,000-900rpm but as soon as i touch the throttle and drive thats where the issues happen.

If I stop in traffic or have the car in neutral the car will idle at around 600-500 rpm and sometimes dip lower and cut out.

So far I have changed:

• Lambda Sensor
• ICV
• Throttle Body
• Map Sensor

Within the last month

And within the last 4-5 months I've changed:

• Coilpack
• HT Leads
• Spark Plugs
• Crank Sensor

Does anyone have any ideas what could be causing this real annoying issue?

Thanks

Throttle position sensor... The plastic bit inside gets worn
