strange BOV related? mixture problem...

[EVL20V]

car: celica gt4 st185 1990

ok got bov installed a while back...........not 2 much dramas apart from the odd pop out zorst at gear change etc..........noticed idle went 800-1000 to 400-1000 etc so looked at bov and it was opening and closing at idle.........so made it run rich/lean/shagd?........so i just ignored it and drove fine like that for 2 weeks, then one day drive of with nearly full throttle... ......it jerks, turns lights/stereo off and pops out exhaust........sometimes jumps it outta gear - basically turns car off for 1 sec then turns it on again and im like WTF!........noticed this in 1st sometimes 2nd on above average acceleration .......so i pulled BOV apart and put washers(supplied with BOV) in there 2 tighten spring.......it made idle etc better but spring still moves 5mm at idle.......... the more i put washers in2 tighten it the less noise i get - pointless hahaha. wots the deal here?

I almost passed out reading your post due to lack of oxygen. Punctuation is your friend.

im thinking boost leak triggering fuel cut?
funny idle sounds like a vacuum leak.which is probly ur bov or related to it.
the cutting out sounds like it could be fuel cut which is triggered at 14.5 odd psi. does it cut out above 1psi after it cuts the first time and not go back to normal til you've restarted the engine?

Total guess here.

Some Toyota fuel pumps are switched on and off by the AFM and are off at idle. If your blowoff valve is causing a vacuum leak then the fuel pump might not be switching on soon enough when you rev above idle so you run out of fuel.

he already knows whats wrong.

YOU HAVE AN ATMOSPHERIC BLOW OFF VALVE, ON AN ENGINE WITH AN AIRFLOW METER NOT DESIGNED FOR AN ATMOSPHERIC BLOW OFF VALVE.

in short, remove it, put a plumb back on, and all the problems you listed (popping outta gear is an odd one though), bar one, will go away.



someone should have listened to cozmo from day one >.>
