Today I started my car waited about a minute for it to warm up (it had only been sitting about an hour). I pull out and the car bogs like crazy for a few seconds and then drives normal the rest of the ride. It was very strange. It happens every once in awhile. Any ideas ? Car has new fuel pump, fuel filter. Plugs,cap,rotor and wires are all fairly new less than 10k on em. Also the car had about 3/4 of a tank of gas(sunoco 93 octane w/ stp injector cleaner).

try pulling the 02 sensor(s) and seeing how clean they are - or their condition... i'm not sure what people have tried in the past to clean them up, but perhaps cleaning or replacing them might help... it's a shot in the dark, but sounds like you've got the rest somewhat covered.

failing that... maybe bad gas?

No its usually only right when I start moving after parked. It will hesitation and the rpms will just sit and then all of a sudden the car willl start moving. Its weird. I doubt it would be bad gas, ive been using sunoco only for about a year and have had no problems....but i guess its still a possibilty.

How would i clean the o2 ? Ive heard using a torch and also using seafoam but idk how much i trust either of those ways.

 

why clean a 30 dollar sensor when you can just buy it. I would rather have a new one.

 

$30 ...from where ? I remember asking awhile back just to know and autozone wanted over $100 per sensor.

And it has to be for an SH... i believe they are different.

i think you can get non-denso sensors for cheaper - but i've also heard they "can" be problematic (results appear to vary)... but here in CAN, at the honda dealership i think I paid like 200 bucks for my denso 02 sensor - i got a 4th gen so i only got the one.

i'm not sure 98sh - maybe someone else will pipe up about the cleanin bit... i'd say just have a look at it to start - maybe the thing is disintegrated - mine was partially disintegrated and didn't trip a cell... however - how is your gas mileage - i would think that would be negatively affected if your 02 was on the way out.

 

Its not great.... but i also dont drive nice all the time so i havent really gotten a good calculation
