Chrysler Repair: Stuttering while accelerating: 92 2.2L turbo, fixing cars, drb ii

Question
QUESTION: 1992 laser stuters when the boost indicator hits around 7 lb/in2 while accelerating

ANSWER: Hi Michael,
Have you tried for fault codes? "on-off-on-off-on and leave on" with the ignition key, doing that in 5 seconds or less elapsed time? Then watch the power loss light, which remains 'on', to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat to assure an accurate flach count. Then tell the counts in order of appearance and we'll go on from that point. These are the codes relevant to all the engines, but not the extra codes for the turbo engines.
There is also a turbo diagnostic procedure that requires the Chrysler Diagnostic Readout Box II. I have the manual for the '92 Turbo III procedures so if you can get someone to do a readout with a DRB II and get a specific trouble code I can then photocopy the pages that show how to deal with that code. Is yours a "Turbo III"?

QUESTION: I know it's a  factory turbo but I don't know if it's a turbo III. My roommate has a diagnostics scanner that he uses for fixing cars, a hand held computer like item, which I would think would work on this car. I just haven't gotten him to hook it up yet. The repair manual that I have gives me a few things to trouble shoot like spark plugs, or cleaning the injectors. I was just thinking though that if it was the plugs it would be causing the problem through out the RPM rang. I was gonna change the plugs first and then if that didn't work go for the injectors. It also says that it could be the fuel filter, I'm under the impression that it might be the injectors, thinking as the force or pressure increases from the turbo it's causing the debree to be pushed into the injectors causing a decrees in fuel flow. Let me know what you think about that and I'll try your suggestion and see what codes it gives me.

Thank you
Mike

Answer
Hi Michael,
Try the ignition key on-off routine first and see what that shows. Then ask the roommate to give it a try with his reader. Then decide what parts to replace, unless you know that some are past their normal lifetime. I'll be interested in the results.
