Good morning PP’ers,
I hope such a request is permissible!!!
I’d like to put out a call to see if there is anyone in the Brisbane area that would have Techstream and would be able to help me with a quick analysis of my car. Am happy to pay in beer!!
am keen to get a full capture of values for the vehicle to help with next decisions regarding a PAINFUL recurring issue.
Car is:
- 1kd 2007
- 213km
- auto
Fault:
- whether hot or cold, there is a fairly significant amount of surging occurring at 2100rpm, 2300rpm and 2400rpm.
- no issues evident at other rpm ranges
- repeatable every drive.
- am concerned that this is damaging the engine.
- NO fault codes
I have:
- checked and cleaned heaps of electrical connections
- cleaned MAP and MAF sensors and filters, cold start idle values look ok.
- cleaned EGR valve and manifold (but not the cooler).
- turbo and stepper replaced at about 190k
- fuel filters and air filters recently replaced.
Thoughts on next steps:
- keen to measure TPS values through the full rev range (hence need for techstream)
- cross check on fuel delivery pressures (SCV?).
- check injector values
I would be absolutely grateful for any assistance with accessing techstream and with advice on where to look next.
kind regards.
