Background info: Recently I had some threads regarding my car (MY2002 50,000miles) misfiring at idle with no CEL present. I through in a set of used AP2 injectors after looking at every other possible thing it could be and the car now idles 100% flawlessly and has never misfired since. I have also noticed quite a bit better fuel economy as well so I know the old injectors were definitely a problem.

I am now noticing a new problem that "may" have been there before slightly but seems to be getting much worse now...Under certain mild acceleration (low rpm) I am getting a type of bogging that almost feels like I am running out of fuel when I press the gas. The car somewhat delays a second and then you feel it get the fuel and it goes. This is ONLY under low rpm with half or less throttle conditions. The car revs perfectly and strong up to redline with no problem at all. Is it possible the used injectors could have solved one problem and created another? Is there something that is commonly not installed correctly when changing injectors? I have no CEL once again and this bogging occurrence does not even happen that frequently, but it is very evident when it does with an annoying delay.


Any ideas of things to check would be greatly appreciated.


So far I have recently done the following:
- Map whack/zip tie fix
- new plugs gapped correctly

 

 

Sounds like it could be an Ignition Coil issue. Best bet would be to get it along to a dealer for a proper diagnostic.

 

I have actually never needed to bring any of my cars to a dealership ever and consider myself a fairly skilled DIY mechanic (with the help of all you guys of course! Out of curiousity what equipment do they have that could help diagnose this problem?

 

this may be a long shot but have you checked the throttle cable for proper tension? If there is too much slack it is possible that you could experience something like this. if you do have to adjust it dont make it too tight there should be a small amount of slack in the cable.
