Ive been having some bad idle problems for a while and today i went and pinched the vacum line to the EGR while my car was idling bad and nothing different happend. does this mean my EGR is bad? and i have no emmisions left anyways so is it hard to block that off and will it affect anything else at all? thanks for any advise.


Cowzzz

 

Doesn't mean a thing. Disconnecting that vacuum line should result ina vacuum leak, but preventing the EGR from operating won't effect engine operation. The only rotaries to actually have EGR are the California 12A, and the '85-'88 13B.

If you have no emissions, you might as well remove the EGR valve entirely, block it off, and then cap off the vacuum nipple.

 

I have a 88 t2 and thanks for the advice. i orderd the block off tonite. now i just gotta try and figure the idle problem out again.

 

Disconnecting the vac line, and unplugging the connector from the EGR solenoid valve, shouldn't result in a leak at all.

If your EGR valve is totally shot (bypassing gases internally 100% of the time), it makes no difference if it's got a vac supply or not- your exhaust gases are blowing past the internal plunger and straight into the intake passages. Kind of like what was happening with my block-off plate...

 

Another quck question....i just oreded the block of plate for it and i went outside to look at the egr...and i couldnt see any bolts holding it on. i stuck my hand back their and i couldnt feel anything either. am i going to have to take somthing off in order to get the EGR off as well?????

 

you already have your intake manifold off to get to it right? or are you looking at something else that isnt the egr, there should be 1 bolt on one corner of it and a stud with a nut on the other corner of it.

 

no intake manifold isnt off...i know its the EGR valve. it is right above my down pipe. i just cant see any bolts or studs to get it off.
