1991 Nissan Maxima Q&A
1991 Nissan Maxima Question: dead cylinder
my car is sucking and blowing thrue the exaust like a blown head gasket but got good compresion n all 6 cylinders can a vacume leak cause this - Visitor
Yes, vacuum leaks can cause misfire. Start the engine raise the hood and listen for hissing sound from air leak. You may need a shop with a smoke machine to find it quick for you. Also check for bad fuel injector, these cars had problems with that. - torque wrench
usually when you have vacuum in the exhaust with a miss, it has a bad exhaust valve. have a leakdown test performed to confirm. Roy - mastertech6371
