SmashedGlass Posted June 17, 2012 Share Posted June 17, 2012 Yesterday I tore apart my intake system along with all the PCV related hoses to clean it out, as it had some oil build up in it (PCV itself was changed a few weeks ago). I carefully cleaned the MAF with CRC MAF cleaner; then sprayed out the intake snorkel and the hoses with some degreaser then rinsed well with water, also knocking quite a bit of carbon build-up out of the drivers side PCV hose; then wiped everything out really good and allowed them to dry overnight. Replaced air filter this morning to complete the project, and now my car has a dead, laggy spot around 3000rpm and sometimes idles low and erratically. This is on an 88 SPFI 5sp. Any ideas? Should I just drive the crap out of it to see if it clears, run some Sea Foam through the intake, or something else? Link to comment Share on other sites More sharing options...
djellum Posted June 17, 2012 Share Posted June 17, 2012 nothings more likely to be broken than after you mess with it. Id go back through the PCV system and see if you created a leak or allowed some of the carbon to get sucked into the valve or something. Personally i would just go replace the hose, it costs about $1.99 for some generic pcv hose and you know theres nothing in it. while its out take the pcv out and wash it in gas and make sure its functioning. also an air leak after the MAF can cause issues, Id just double check.
