Annoying problem D16z6!! HELP
 

check engine light been coming on alot more (since the weather got warmer) could temp effect this problem???? im so confused..

Problem: Check eng will come on (car runs decent), now when the check eng. sometimes dont come on it sometimes acts up. Heres what it does:

How i know its gonna run crappy: i will push on the gas very lightly and around 1200-1400 rpms it will start idling rough Ex: vroom vroom vroom.

Now when i start off i go as i normally would and the idle drops down and almost stalls (sometimes does!!!!) now it goes real low then shoots up to 3k+ rpm then goes.

When im driving it rides soooo rough. ill let off the gas and then give it gas and it jolts!

Whats even stranger is it usually just goes away then my car will run normal again?! All this usually happens after the car is already warm....I will go drive the car for the 1st time in the day and it runs ok, check eng. still comes on. but lets say i shut off the car and turn it back on then it usually acts up!!! i just dont know what the problem could be... could it be something with the ign.? anyone know?


I just changed the o2 sensor/ PCV/ Replaced the entire fuel system (fuel rail injectors, etc.)

What could it be?!!?

just did an engine check... for some reason my voltage is going crazy when it acts up. any ideas why? checked o2 sensor with a scan tool and it showed when i give it gas the voltage went whack then when i let off it went back up to normal.

Numbers: Normal. 800
When giving it gas: 40-60

Why not retrieve the engine code and go from there? Did I miss something?

well fixed osme thing yesterday!
First i found out how to check the code. what i did was when the car was on the check eng. came on so i was like lemme try to jump it now. so i did and it flashed a code 6 which is coolent temp sensor. so i had one on my spare eng. and boom no more check eng!!

I still get those weird surges though but today im gonna adjust the IACV, TPS, etc and see if that works.... Another thing was my ing. timing was pretty retard so now thats all fixed and car is running 10x better! But still acts up https://honda-tech.com/forums/images/smilies/emsad.gif
