Whats goin on ppl. Well i have a 95 hb with a b18c swap. Sometime my car pulls weak when its warmed up and pulls hard when it not fully warmed up. Whats up with that. Ive changed my dizzy rotor and it felt better, then like 2 weeks later its started acting up again. U guys think its a fuel problem or ign? what should I do? and my temp gauge was kinda of workin then drop to cold. chaged the thermostat and now its the temp gauge isnt even working period. the sensor is pluged.(bad sensor?)*** me right?

B.

what ecu is in the car?

PphamEK

stock p72

B.

how long ago did you do the swap?

PphamEK

Like around 2 yrs now. like ur Eg man ***** sexy

B.

thanks man. 2 yrs, hmm there goes my suggestions lol. IMO take it somewhere and have it looked at. It's hard for me to really understand the issues unless I can see/hear the car. Sorry man. Good luck.

PphamEK

yea, i was thinkin of that. well thanks anyways, its worth a try

you may need to have your ecu tuned to understand the fuel and air it should be getting. Since you didn't mention any misfiring, that may exclude any ignition issues. You may just be running lean or rich depending on the outside air temp. (my opinion)

Have a compression test done and see if any cylinders are misfiring.

PphamEK

really? but the ecu is for that motor... so shouldnt it already understand the air and fuel mixture?

PphamEK

yea ima try that out. whats gud compression like 180?

you have a b18c with a usdm p72?

my d15b had a problem similar to this one. It was my IAT sensor getting heatsoaked, and thats caused the ecu to retard my timing over 5 deg. ECU retards timing when it see air temp over 130

i belive its ajdm p72

IC where is the IAT located at in a b series? and how can u tell if it messed up?
