problems with Opel injectors?

So i got my new injectores in and put them on, got tuned, everything was running pretty good for a day or 2, then started to get a misfire. Changed out the plugs and same thing, and it would get worst and worst.

brought it to the garage and did a leak down and a Compression test and both checked out fine. Pulled out the new injetores and installed the old onesand they worked perfect, reinstalled the opel and misfires right away

Any idea????????????

Leak down would have shown a bad seal, no?

Log the injector pulse widths on all cylinders and see if there are any noticeable differences between 1 and 2 vs 3 and 4. If it's ONLY missing on 1 and 2, try swapping injectors 3 and 4 to the 1 and 2 position. If any odd pulse widths and misfires follow the injectors, then it's likely an injector or seal issue. Do the logging yourself and see the results for yourself to ensure there are no.... umm.... biased or impartial interpretation of the results.

i see what you did there.

If the injector data is not right, it will misfire.

good luck!

I have gone down this road and fixed a couple Opel injector scaling issues for others.
