99 integra misfire codes
new to this site. I just bought a 99 teg with a b18c1. check engine light is on (I figured due to o2 sensor). didn't think it was a big deal because the car ran fine. no rough idle. all gears pull hard. vtec hits every time. took it to a shop to have it checked out. threw quite a few codes including o2 sensor, crankshaft sensor and misfire on all cyllinders. ive read a few posts on here but im just wondering which direction to go in. compression check, timing, injectors, vaccum leak? I plan on doing a full tune up next week. hoping it takes care of the issue but until then id appreciate the help!

Re: 99 integra misfire codes
First take care of all the codes! depending on which o2 sensor usually bank 1 which is the o2 sensor closest to the engine on the cat converter.
Check the crank shaft fluctuating sensor ( CFP) it might need to be replaced or the wires are shredded causing the code to pop, Its behind the lower timing belt cover bolted to the oil pump.
BUT i don't think its that sensor thats pulling the code its the crank shaft position sensor ( CKP) thats located inside the distributor. This can also explain the miss fires you have.
Replace those and clear the code and or reset the ECU by unplugging it for a few mins and see how it runs or if the codes go away.
