Fuel injectors failing on Carina 7A-FE engine

I bought a Toyota Carina about 12 months ago - after a couple of months, the engine begin misfiring at times when I'd say the engine would be hotter than normal - i.e. - when I put my foot down uphills, leaving the engine off for a few minutes after it had been operating normally, then switching back on. After replacing all sorts of bits (distributot cap/arm, injector cleaner), it was traced to a faulty fuel injector which was replaced (#3 cylinder). About a month later, #2 did the same. That was replaced and all was fine. The faulty injector was ultrasonically cleaned, and came through with a clean bill of health. When #1 injector started going faulty, I replaced it with the cleaned injector - that failed immediately, so was replaced. Now #4 injector appears to be going & the scrapyard's run out of these "blue" injectors (odd in itself).

This fault only happens intermittently, when the engine is "hot" - I am not losing any water, nor is the temp gauge showing overheating of any kind.

Does anyone have any idea whats wrong ? I've had it into a toyota dealer & another garage - no luck.

I am having exactly the same type of fault as described by Paul. Did you get a solution? Any suggestions anyone?

I suspect that most people remember Paul or his faults, or know you or your faults. Therefore, I suggest that the next time you are looking for answers or solutions, you leave the original text in your post to refresh peoples' memories.
