Yea, me too.... I hate to go to the Dealership even though I have warranty, I always get dicked around and takes them forever. I may just buy a new MAP, a 255 lph fuel pump and plugs and be done with it. It feels like a fuel problem like its starving for fuel.

 

dirty injectors?

 

No CEL?

Sounds like with that much trouble the ECM would be complaining.

I had an erratic misfire at no particular rpm or load, turned out to be a bad coil pack.

 

Ok, so after work in going to pick up another MAP sensor and try it out to see if that corrects the problem. No CEL and I know the MAP will jack up without throwing a code. I'm also going to check my filter for any excess debris. I'm going to pull my plugs when I get home to look for any unusual signs of leaning out or too rich...but I'm hoping it is just the MAP.

 

update** I put another MAP sensor on yesterday and the car pulled all the way to redline this morning on the way to work. I'm gonna keep driving on this MAP to make sure that's the fix.

I also hit my old MAP before I went home yesterday and it didn't act up on my way home at least, vtec'd it once and no hesitation.
