Intermittent running problems
Hi everyone, should probably start this off with a bit of background info.
this is my back and fourth to work car, i do have a lead foot sometimes, but I don't need it for the power.
my r33 non turbo automatic with the RB25DE has been running rough intermittently
when it first started
I thought it might have been a fuel issue, so changed the fuel filter, oil, oil filter and blew out the air filter
i pulled the coil packs out and they were starting to show small problems
Problem continued
, had to wait a few days to fix that but finally got round to it, cleaned the carby and mass flow, the spark plugs i had thought should be still good since the last service not many k's before but a fair amount of time
it drove smooth the next day, then started to drive rough 30mins in the day after.
i pulled it apart again deciding to change the plugs, chucked carby cleaner
drove the next day calmly, day later ran rough 35mins into drive
decided the coolant temperature sensor needed to be replaced
drove to and from work smoothly
then jumped in to run down the road and it didn't just wait to be 10 or 15 mins into the drive, it ran rough all the way
