When printing scope traces using rulers etc, the legends don't print. After printing, the channel labels underneath the scope traces A,B,C and D are not colour coded like the rulers, therefore make the presentation difficult to decide which ruler applies to which channel. Would it be possible to upd...

B/ What component in a cylinder can cause intermittent compression problems when the engine is cold some mornings and other mornings the engine starts and runs okay for days on end. Maybe take a look for coolant in the cylinder in the morning - that would fit your symptoms. - Inc shorting out the p...

Thank you for your reply and advice. I've devised a test plan to check the electrics, coils and injection circuits based on your advice and wiring diagram. Looking at the wiring diagram I'm thinking the current demand for the coils and injectors should be around 8 - 10A each circuit. I'm clearly not...

Car came in with engine misfire, which only occurs from cold and last a few seconds, but if the engine is accelerated during the misfire, it clears and does not return. I've tried previously to upload PS data files but they are too big, hence I need to know how to cut sections of the recording for u...

Mr Dalton has hit the nail on the head ! It seems that there is a shift in the "technicians" thinking. With the purchase of a Scan tool the expectation was very simple: What sensor do I replace to fix this car ? Now, months, years, decades later, the scan tool didn't live up to the promise, that on...

How does one upload files these days when the files are too big!

20230731_121858.jpg History... Five years approximately ago the engine was rebuilt because of a failed oil cooler. No expense was spared, whatever was required was carried out. Five years later cylinder 3 is misfiring when cold only, which soon clears. I'll upload files later, but I don't think WPS...

Thanks Danny, next time I have a misfiring engine injector relalated I do just that. That is provided I can remember cylinder 1 is at the flywheel end

I also invested in the sonic belt tensioning tool by Gates, this was the same as above picture going back to the late 1990's. The selling point for that tool at the time was, "Any engine that fails in service because of our belt fitted and tensioned by our tool, we will replace the engine for free"....

Car came in two weeks ago and boss looed at it said it was misfiring on cylinder 3. I used the scanner Apolo 8 read codes and live data and the information advised cylinder 3 injector circuit fault. I was asked to fit a new injector into cylinder 3. Not checking the technical data first and thinking...
