ever since one hard highway pull yesterday my car has been driving like **** (highway pull of 90-130km/h in 4th)

now i'll be driving and the car will feel like its absolutly lost all power, gas to teh floor and doesnt move, all of a sudden it feels like someone dumped teh clutch and throws your head back and starts accelerating like normal

I automatically thought fuel filter or clogged MAP sensor... went home changed the fuel filter and cleraned out the MAP and hose going to the MAP

problem still exists worse than ever... and now it feels like all the time has a bit less power all the time


Please make an E-diagnosis for me! I really need the car to work right again, the 90km highway return trip to work is killing me like this

PS: the car is a 92 civic sedan, 5 speed, OBD1, d15b7 head, d15b2 bottom end..... only thing done to it is a filter on teh end of the stock intake tube

 

measure how long it takes to accelerate a few times.....


maybe nothings changed your just used to the power happened to me, i got used to my b16 in like 1 month i thought it was gettin slow as well but no, rather i got used to it same 15 sec 1/4 mile just used to the power was all it was

 

no i 100% know that im loosing fuel becaus ethe motor dies out and then picks back up like if you were to put the clutch in rev it up and dump the clutch on teh highway, thats how hard it jerks the car when fuel starts flowing again

 

same exact problem that happened to me.. after a while of not figuring it out i put mine in the shop and as of right now all he said was its losing fuel pressure and he hasnt gotten it fixed yet but ill tell you what my problem turns out to be
