'87 760T (USA) no power leaving stoplight
Reviving a pretty Brick; my 3rd and most challenging, supposedly needing only the underhood wiring harness, previously done on a N/A 245.
The car runs nicely, now, starts right up; idles smoothly. Mileage is 155k. Other background, below. AT shifts crisply.
When warmed up, there is almost no engine power below 1500 RPM, with little/no boost indicted. Boost seems normal, in other driving, as long as the RPM stays up. The turbo finger-spins easily, with no play felt; cold, of course. I haven't means (yet) to check FP or ECU for codes, despite Haynes(ugh) and FAQ resources. There's minimal oil in ducting downstream from turbo, nor discernible boost leaks from that piping and no audibles. I modified the heat input and made a rubber gasket to further seal out hot air from the air box. Unless leaving a stop, the car drives well, above 2200 RPM.
The FPR seems new with no gas in the vacuum line, but there is no idle change when I apply vacuum. Both fuel pumps operate.
A PO scraped away much of the AMM screen, but visually, the guts seem fine. The vacuum operated (wastegate?) unit on the turbo looks fairly new. The engine pulls good vacuum at idle, with minor fluctuation, which may indicate a valve clearance issue.
I read this: http://forums.turbobricks.com/showthread.php?t=330754 and the few other threads found.
I spent lots of time getting it started, replacing the power stage(?) on the L inner fenderwell, yet found no spark past the new coil wire; took new cap and rotor, despite the 'old' being brand new (PO). Got the O/D working with the home brew mod to the solenoid cap, and tweaked the cable for proper shifting. Plugs wires look new, Volvo brand.
Sorted out other electrical issues incl shoddy aftermarket radio install plus lots of hard plastic repairs/replacements, The leather is as gorgeous in red as the exterior white paint is!
Not interested in throwing parts at it. Appreciate help,whether links or experiences!
