UK Auto Repair Questions?
Has the battery ever been disconnected or any work done on the engine prior to this problem?
Any engine warning lights on?
ok..sometime if the battery has been disconnected or throttle body removed at any point for cleaning it can upset the throotle position in which it will have to be readapted using a scanner...so bear that in mind..from what your saying regarding the high pitched noise..id certainly be looking at a possible vaccum or intake leakcausing the engine idle speed to increase..twin ports can be prone to inlet manifold issues,carbon build up..so tracing that down and then make a carefull inspection of the the entire intake system starting at the filter follow the pipe work checking for breaks or leaks in the tube..check all small vaccum lines to inlet,ideally a smoke machine test on the intake vaccum system would for sure highlight any leaks especially if the inlet gasket is leaking when the engine reaches temperature,heat expansion....so a few things to have checked out anyway..hop e this helps
Pretty hard to guage and would be a bit premature to speculate if nothing has been checked,inspected yet. that based on garage labour rates differing in each area plus their expertise too...this check in ideal situations with the correct equipment plus knowing what they are doing and checking for .. about an 1hr and half labor..so maybe £40 approx diagnosing..if anything £150max...like i say if they smoke machine tester..they can induce smoke into the vac,intake,egr system..that would cut the time checks wise for sure...or they dont have one.they could look at the live data on scanner fuel trims, or carefully go around joins,seems on the intake,vac,egr with some carb cleaner,brake clean,to see if the idle changes somewhat...
No problem..hope you get it sorted out...if you could leave a rating for me it would much appreciated..thanks you
