new760Liowner: I have not scanned myself with INPA. I had the mechanic run a scan. Mechanic told me that the HPFP is measured in BARS and should be 120, converted to PSI it should be 1,740.
I have replaced both fuel filters and the fuel pump.
There is no way to tell if the carbon cleaning has improved anything since I cannot drive car more than a few miles at a time.
Gadget760Li: I have not replaced the IGM which in the US is the Integrated Power Supply Module, part number 12527510638. Matching your jpeg. That one thing I was going try, and then the Crankshaft Speed Sensor. Tell me what you want for the part and we can do the deal on PayPal.
I found a HPFP on eBay for $400.00. Problem is I do not think replacing the HPFPs is a DIY job.
