ok so ive noticed this but not as bad as now its starting to get on my nerves..........my car seems to run very rich and is getting aobut 20miles a gallon wich is terrible for a d15b2 ok well when im in second gear at about 2000 rpms and i floor it it bogs down and starting to speed up and when im in 3rd at 2000 it bogs bad till a out 4000...what can i do to fix this ???

 

I wouldn't know for sure but maybe your car is running super rich due to an o2 sensor? I my car was getting horrible gas mileage, around 25-27 and I put one in and now I am getting between 33-37 per gallon now. Could try that!

 

hmm. mine seems to bog a little in the lower rpm ranges (2000-3000) but really kicks in after that. Would it have anything to do with my o2 mapping sensor thing. I ask this because the o2 maping sensor on the top of the intake (my engine is from a 96 civ) is not plugged in at all.

if theres any merrit, could be that.

 

my car is smoking really bad after 5000rpms in first and it smokes at 3000 rpms in 2nd

 

what colour smoke.

also, to avoid boggin in 2nd when u floor it @ 2,000rpm try downshifting

 

like a white or a blueish lol i also have a stock exaust from 1988

 

check your grounding? Mine was jacked...acted like it was'nt getting fuel/spark to a few pistons when you would try to rev it, and after a few seconds of bogging/acting like it wanted to stall, it would catch and rev up....but it seemed to idle ok...and when you really pushed the gas, it would rev up after a sec of bogging, but if you held it at a certain rpm, it would run fine, and then you try to rev it up a lil more, it would drop before it would rasie the rpms....So, after a COMPLETE expensive tuneup, I was lost for ideas...So, I got to looking and my grounding straps, both the one from the battery to the frame/tranny and the one from the valve cover to the radiator cross member thingy where nasty and frayed. So, I replaced them, and it fixed my problem. I could'nt find replacements, so I had to make my own:



Oh, and it would also smoke, similar to what you explained....May be worth at least checking???

 

i really dont even think i have a ground at at all
