just got a b16 swapped in a couple weeks ago, and earlier this week i noticed that when i accelerate off in first, it boggs until 1800 rpms. Any suggestions?

 

did u adjust your valves

 

after the swap, yup

 

I have been chasing my bogging problems for months, I decided (after replacing every other part on the car) now that I have broken vavle springs and it is not opening and closing some of the valves correctly. O2 sensors seem to be pretty common problems though...

 

either of u try a new fpr used or wutever

 

could be electrical
check compression
check fuel filter and fuel lines for clogs and stuff
check catalytic converter, maybe clogged when you did the swap.
check 02 sensor
thats all I can think of for now

 

jdmb18hatch...already changed it thanks, Veil_side...I check all electrical I could think of replaced cap, rotor, coil, ignitor (it went bad anyway), plugs, wires, etc., compression is 200 across the board, new fuel filter and lines flushed a few times, cat is gutted, and two brand new Bosch O2 sensors...Thanks though

 

i just swaped a motor in also and i'm having the same problem. anyone?

 

kinda stupid to bring up...but just a reminder...
got new spark plugs + wires + oil + belts + water pump right?

 

yeah, went through all of that already

 

yeah, me too, anything else??

 

some people are telling me to get my valves adjusted.

 

Another simple one, are all your grounds connected? I know for sure there should be 3, I have heard 4 though. Just a thought.

 

would that cause bogging, my car doesnt bog but is slow as ****, and dont know why. I think i might have auto cams in it. Watcha think?

 

if youre runnig two o2 sensors, unplug them both and see how it works. If that stops the bogging just flip either the o2 sensors or (the wires for the o2 sensors at the ecu). It worked like a charm for me.

 

have you checked your fuel pressure? your stock pump may not be giving you enough. i swapped my pump out for an h22a pump.

 

I will check the pressure this weekend, but once it hits higher revs its fine. I would imagine that the car would starve up top also and not just on the bottom end right??

 

Did you adjust the timing?

 

I have adjusted the timing and idle at least twice to look for a difference. Anything else.......

 

it sounds like fuel delivery to tell u the truth. maybe ur pump is on the way out. but be sure u have good fuel pressure. it could be clogged injecters to have u checked them?

 

mine is doing the same, so i just take the o2 sensors off? wouldn' tthat throw up codes? then put them on backwards?
