alright, i got my swap all done and have been driving the car normally for a week. lately ive started to bag on it quite a bit. what ive noticed is that the engine tends to bog when i start rolling in 1st at low rpms and i lay on the throttle. the car will buck as if it was driven by a guy who doesnt know how to drive standard. i am not running any codes at all aswell.

i reused the same o2 sensor from my d15b7 which was working normally at the time. i also reused the same spark plugs from the d15b7 (same part number) which are 1 yr old. fuel filter is the same one which also worked fine when the d15b7 was in.

i have also noticed that the gas pedal (throttle) takes more strength to push in initally, but after that its pretty smooth, unlike the gradual engagement of the pedal before the swap.

i have a feeling its to do with my fuel pressure. when i hooked the fuel hose to the fuel filter i torqued the bolt back to spec. will the fuel pressure change as i disonnected the hose from the filter?

sorry for the long post, but im slighty stumped

thanks in advance

 

Did you change your fuel filter when you did the swap? I have bogging problems with my b18b1 swap usually after start up in first gear and it was a result of a clogged fuel filter.

 

first things i'd check,
ignition timing,
cam/crank timing
tps setting
take a peek at ur plugs

 

Clean out your throttle body with Air Intake Cleaner. Its probably filthy in there

 

i think its your TPS...while just liein on the gas on my car...just crusin it..it would bog...and i didn't know why..i have One CEl and its b/c of my ecu...but my TPS has always been okay.....so i unplugged the TPS for gigs and it runs fine now.....doesn't really idle well...but it runs better then b4...so i'm gonna take the TB off tommarow and clean it thoroly
