Alright guys, before i start YES, i did search to find the answer to my problem. but everyone had a little bit different issues and from the things ive learned and tried it did not resolve my issue.
ok i have a 91 318 with a NV m50 swap.
My issues is brakes and sometimes..idle. when the car is off the brakes are very firm, a couple pumps (and by pump i mean maybe have travel of pedal) and brakes are completely firm. when i fire up the car the brake pedal falls about half way (which i believe is pretty normal)
my problem only occurs under 20% power i would say. if im going like 35 and apply brakes they are firm, and once power falls they will fluctuate, maybe get jittering, mushy then firm. This is is why i think its a vacuum issue where the pedal will go from mushy to firm.
i looked for vacuum leaks could not see any holes in the hoses (I will try starter fluid trick later this week).
I have taken out the ICV, and gave it a good clean, after replacing it, it worked! for about a day, brakes even felt better. Can the ICV affect the brakes too?
also applying brakes at low speeds, <10mph the brakes will chatter (firm then mushy then firm)and car will stall out. this doesnt happen all the time, but if i take it out for an hour it could happen 2-3 times. kinda dangerous :/ sometimes starting for the first time i will get idle jump too, up and down.
anyone else have any guesses? car has the 91 318 brake booster installed.
