i have a 1990 civic hatchback dx, stock d15b2 5 speed. i recently went into limp mode .
after my research i purchased a new (used) distributor, iam no longer in limp mode.
i have since adding new part, installed it and pulled ecu fuse as told to reset ecu..
my car feels like it is running better and smells like its not burning as rich (this is a good thing)
but when looking at my ecu i still have cel code 8....???? is there any other reason i could be throwing this code?

i also have code 1- (o2 sensor, it is new about a month old maybe i ruined it burning so rich?)
code 8- (tdc sensor, was told to fix it replace distributor, did that got out of limp mode but code still present)
code 17-(vss- the worst of them all as i have never found a true fix for this anywhere online)

this all happened yesterday i will be taking car for test drive today to see what happens. because somewhere between going into limp mode and installing a new distributor i got the surging idle.
i dont know if it was something that happened once or if its going to be reoccurring....
this is my 1st post here and any information to help would be great thanks

ok just got back from drive. my car did something new and the temp gauge went up about half way which never happens..... but the idle surge is real i have videos on youtube for reference . there is a 1/2 tube coming of the right side o the dpfi that when i squeeze it closed it stops the surge . hope this helps .
--this video shows how surge stops when i squeeze tube
-- this video is the exhaust , so you have ore of an audio

 

The surge looks like a vacuum leak to me. Why is the hose clamp 1/2 way up the tube? Need to make sure the clamps are in place and that hose has no cracks/holes. Check your mechanical and electrical timing.

 

Thanks for the reply. Hose clams has been put into the proper location. Iacv has been cleaned. Today I will buy some carb cleaner trying to locate hose leak

 

no vacuum leaks detected visually or using carb cleaner

 

update. all vac lines check no leaks. new iacv installed no deference. i saw a video on utube where the guy loosened a nut from his throttle and that worked for a minute then came back please help

 

update again i have burped the coolant system and made sure to include the heater core , still no luck.

 

 

in addition iam still throwing cel codes
*1- o2 sensor- is new but maybe went bad
*8- tdc sensor- replaced distributor , dont know what to do next
*17- vss- i have never found a real fix for this
