Ok here are the issues...when there's a cold start i have to tap the gas to stay on.at first then it idles rough..if i dont it sounds like its running on 3 cylinders
then dies..after that its fine....the vac pres would be at 20 vac at 800-1k but then it drops to 400-300k the the vac drops to 12-13..I did pressure test the system i found leaks and fixed it ...BUT when i pressure the system to 20-25 i get a leak at the adj FPR it seems the it leaks a lil at the top bolt to hold the adjustment....engine comp is good,i adjusted idle but still happens..timing is good.and i change the temp senor..spark plugs i have to double check...in the morning before i start the car to see if its wet with fuel...does this sound like a leaky injector...
ok.. i pulled the rail and none of the injectors were leaking ...but i did notice one spacer is missing..the one next the injector 3 ..and injector 2 was replaced..because all on the injecotrs are grey and # 2 is purple...i know purple injectors r 370's and greys are 333cc:eek2: ...and what if they but na injectors in wouldnt the car not run..if its a u13 ecu since its set to 370?
and should i pull the rail agian when the car is cold to see if that makes a dif since at cold starts this happenes...but at the same time i have that idle problem *** pressure test it agian..im just gonna cap the fpr..to see if i have anymore vac leaks...
