I was driving like normal then my car started boging for a little bit then it stoped so I kept going.then I stop at the store,come back out and my car wont start.its jerking really bad and I noticed smoke coming out of the intake so I stopped trying to start it.so i let it sit for a little bit 10-15min then tried again and car started right up like normal but now white smoke is coming out of the exhaust.after about 10 min of the car running its starts to bogg again.I've checked oil level n its fine,coolant is fine,everything looks normal.now its got pulling my hair .its a ls/vtec in a 98 hb if that helps.
