[pk 84 911]

Please help if you can.

I have just had my 2.7 rebuilt 3000 miles ago. Rebuilt heads, line bore, Rings, Clutch, Injectors +++

The problem is since the rebuild It seems to be clogging injectors. I have flushed the tank run Techron concentrate a few times, cleaned the injectors on a bench clean 3 times.
After the Inj clean it runs extremely smooth, not the slightes stumble on take off, after about 10 miles it starts to stumble then gets progressively worse until I clean the inj again. I use Chevron gas.

I know reason would say it is the injectors clogging up again but after this amount of miles and all the flushings you would think that it should have flushed anything out by now.

Has anyone else experiensed this. Does anyone have any other suggestions. It is really affecting my pleasure of driving this awsome car especially after I think of the $7,000.00 I just spent on it.

Thanks
