hello again and welcome
great work there and that infinite valve lash,, must have been some racket.
seems engine, is ok, good compression and lash,, last too tight can cause compression loss hot.
yes, youtube can hold videos, with magic $10billion server farms, distributed world wide. but sadly, we don't have pace for videos. (huge files)
we are dinky Doo, space.
most my photos are like 150kB. sized... tiny
stATAUS.
runs (BUT A DOG)
engine now good. compression at spec.
flashes 12s, (no sensor fell off. TBI
is engine misfiring at idle?, and engine shaking?
fast right foot, trick saves! stall super easy??, that is lack of air. or tad hard,fights you, this. in park.
what is cold start rpm?
and hot started. after dash pot delays,?
map hose not cracked, not clogged.
ect READ 300 ohms unplugged, fully hot engine, if not then thermostat bad. 180-195 degree stats only worl
ISC valve stuck closed, is my guess now.
idle switch stuck open (TPS not calibrated,) kills ISC dead. 0vdc on switch is correct after dash pot does it delay thing'y
leaking injector or its 2 x 0-rings.
air leaks or vacuum leaks never cause low engine power, in fact opposite, races with full power with leaks.
some other input to ecu bad.
no cracks in exhaust manifold, From bottom of manifold to the CAT brick inside, zero cracks allowed.
good the rhino tool , i have the page that answers this
ECT 180F:?
in closed loop, at hot idle
LTFT i where. centered hot idle 118?
injector pw. hot, at idle, in park.?
idle switch on?
SEE Those other switches, off is correct.
rich lean status?
MAP, 8v, is in Kpa pressure (vacuum) hot idle. park.
seen this page yet this is magic page, a mix of 8v and 16v data, OBD1, all live data. scanned live. from the real FSM book
unlike oBD2, many parameters oddly shown, like LTFT . long term fuel trim

In continuation of replacing my son’s Sidekick’s engine, as per your suggestion in my last thread, I checked the TDC at cylinder 1, at the firing cycle, with the valve lash loose, and that was correct. If you recall, you told me the backfiring I was getting would have been due to the TDC not necessarily having been at cylinder 1 being at its firing cycle, when dizzy’s dial was at 11 PM.
However, what had happened, one of the nuts on one of the valves had come loose! After fixing that and checking all valve lashes, and ensuring that the distributor’s dial is at 11 PM at the TDC at cylinder 1 at firing order (I also used the tool that you have a picture of in one of your pages for establishing a cylinder’s maximum travel to its top; TDC), I started the car. In the beginning there were lots of huffs and puffs (I am not sure whether it is dues to the gas in the car being 8 months old?!) However, after warming up, the number of backfiring sounds diminished to almost zero. However, in comparison to past, the engine vibrates a lot in my opinion. I captured a video of it running; But the site does not allow me to load the file due to its size. I can mount it on my Drobox and send you an email to permit you seeing it; however, for that I need your email! Is there any other way I can sen you the file? Its size is 191 Mb.
When the car is accelerated in PARK, the RPM goes up and everything sounds reasonably OK; however, as soon as it goes to any gear, it shuts off, unless a bit of acceleration is applied. Even then, there is not power, when it is in drive, and it barely reaches 15 MPH, despite the compression test revealed that I have a minimum of 155 psi in each cylinder.
I checked the timing with the strobe light, and it is set at 8 deg. BTDC. I am really baffled as what is the cause of this problem now? I would appreciate receiving your views on this issue.
BTW, I checked engine’s code, and registers 12. I also have Rhino’s cable and software. No particular issue can be seen through that software (although, to be honest, I do not understand the values from most sensors’ reported by the software.
Cheers,
Zackman
