What could cause your turbo and manifold to glow red after an easy drive (hard drive dosent make a difference)?
Hints:
3in full exhaust using crappy elbow
Apexi Power intake
ran like a dog..smooth but no power, a new TPS fixed that.
AFM was taken from a friends car that used to run (RK)
idels at 600-700 and about 900 with AC on
low end power sucks (but its a supra im told)
With ac launching from 2-2.5k necessary
power and response is great from 3+k rpm
engine temp is great
new intake gaskets on the entire side BUT......
Only pulling 10-12 negative on my autometer guage
if i plug ISC car chokes and dies, i dont know anout supras but i thought the throttle body is adjusted for a certian idle and ISC jus finly tunes it...IDK
small exhaust leak, farts alittle between turbo and manifold (will fix later)
get around 16MPG city using AC occasionally
when decelerating it gurgles under 1500RPM to idle
if decelerating from higher RPM usually backfires, sometimes just random
Timing WITH diagnostic block jumpered is at ~10
According to the timing marks at TDC the cams both point up at the mark
all boost leaks were fixed
idels smooth
when driving around and in a low gear i hear a bit of gurgeling in the exhaust around 2k RPM
car is all stock minus intake and exhaust.
Car holds 40PSI fuel and nothing leaks, takes maybe 1hr to relieve all of the preassure
OH! and throws code 21, driving with no O2 sensor maked the same reasults, but im going to fix the code 21 tomorrow, and will report reasults
Id really like to figure this car out, it drives fine minus occasional backfiring and sligish below 1500RPM, i just dont want to melt my head, burn valves, detonate, or melt a piston. i would thing this is related to fuel delivery, i cant see anything else doing this. Maybe the Vac levels have something to do with it, like i said i pull 10-12 fluctuates sometimes lower never higher that 12 unless decellerating. Im going to block off all the vac connections to the manifold and onlt install a vac?boost guage under the hood and see if that helps.
I know its long, but if any of you guys get a chance LMK, im out of ideas
