hi i have a 95 integra ls coupe with 238xxx miles on it... stock engine, clutch and everything.. theres oil leakin from the valve cover and whatnot.. there is coolant lose.. i have no idea.. but i spotted one spot from the upper rad hose that goes into the engine block/head.. anyways today when i start the car up i see blue smoke. not dark dark dark blue.. but light blue.. i was like shitt.. thats a bad sign.. than i rev it up to like 5-6k and u couldn't see anymore smoke.. thats wierd after i rev it up like that.. the rpm kept fluctating from 1500rpm -1700rpm constantly for like 30secs and than back to idle... it idles fine.. the other day i had to do a roll starting. do u guys think its the unburnt fuel left in the cat doing that..


for some reason it doesn;t do this all the time just today.. oh well i plan on rebuilding this LS engine once i go to UTI next year and prepare it to be boost'd when i hit the hotrod and performance class at UTI..

thanks for any tips guys

 

when was the last time all the maintenance was done? belts, fluides, hoses, etc?

 

a weird idle like that could be a bad o2 sensor. get a tuneup done and an oil change. and flush your radiator

Do a basic tune up, clean the motor then check for leaks, it's either the O2 sensor.. even try cleaning out your PCV too..

 

tune up was done last summer so a year ago from today.. timing belt, spark plugs, axles, waterpump.. only theromstat wasn;t changed..


idunno it stopped smoking.. i'mma try and start it up tommorrow and see if i get blue smoke..


like i said i don't get any CEL lights so? plus the fluctating only lasted like 10secs.. probably because i was stomping on the gas to see if any more blue smoke comes out while engine was still cold...

 

start by replacing your thermostat, that can cause the idle fluctuation. You're topped off on coolant right?
