Car: 2002 Acura RSX type-s
Out of the blue today my car hesitates and seems to misfire between 1k-2k RPM. When I start the car it also seems to be rough. at random its fine and other times its not...
I'm guessing it could be:
dirty fuel injectors
bad fuel pump
fuel pressure regulator
fouled sparkplugs
Vacuum leak
prior to this I noticed my car was VERY low on oil...which i dont know why the ECU didn't warn me that I only had like 1.5 quarts of 5! but ok.
Anyone know which problems could be most likely?
I also noticed my mixture has become extra LEAN using my K-pro... so it further emphasizes my guesses...
any thoughts?

Acura Hesitation upon acceleration??
I also have a 02 but i got a k24 block w/ k20 head and it has a bit of a hesitate/sputter on start up and until the engine completely warms up. No idea what it could be

Hello Their,
First thing, inspect ur timing chain tensioner. Im a Honda Technician at Frontier Honda in Colorado.. We have replaced plenty of K-series engine blocks for the same problem(Low Oil), the shaft on the tensioner should not be more or less than 13.5 mm.. The timing chain tensioner is oil pressure controlled.. If u had low oil in ur engine, chances are pretty high that the Chain tensioner collapsed.. A quick way too check too is, remove the valve cover and put the bottom end on time, and check the cam gears to see if the notches line up.. The problem with these K-series engines is the Oil rings... The oil rings collapse causing oil to leak into the combusting chamber.. If u have a BORE SCOPE, inspect the Cyl. walls too. If u see black lines going from the top down, u need bottom end work done..
