Question Engine help !

Hey Guys,
Ive noticed recently my car isnt driving how it use to be. it seems like it started the frist day we got a little nice weather about a few weeks ago... the car would drive like to studering.almost like the gas isnt being spray properly...or the tranny is slipping...i got a GSR swaped in back in january and has been fine...one thing im still running my stock rad from my original engine.. but i dont notice my heat gauge moving going high at all... not sure whats going on. i hope this description helps. its hard to explain.. :s


thanks in advance

lol... stock rad FTW... it is half of what should be there, but i have been running the same thing and i had no overheating issues last summer or well, ever.

sometimes when its hot and i think hot under my hood, when starting it acts a little funny and almost starts on like 3 cylinders or something then kicks in... hasnt happened since i think sept last year and just happened the other day when it was hot...

so i doubt its a prob with the motor... cause it was doin the same thing last summer then stopped and started again... ive been told main relay possibly... who knows...



when is it causing you problems...????
starting, accelerating??? i mean simple hesitation could be just a need of a tune-up... most of those motors have all the original **** in it... if you didn't already change plugs/wires/rotor then do so anyway and see what happens... never hurts to do.




i dunno if you have ever had a honda, but its more noticeable on smaller motors when the lack of oxygen rich air is present (hot days for example)... you running a/c at all?

although, since ive had my swap all last summer and since it was never a bothersome power diff like it was with my d16y7.

while accelerating i notice this...and like you..its not all the time..i really take notice of anything going on weird with the car..i watch this car like a baby...i just got an oil change over the weekend...running Motul 8100...spark plug were done during the swap..wires werent/rotor...so that was my next guess to change...ive had a 90 integra before...this feeling i get while accelerating just doesnt feel right even for the weather...No AC in my car...

thanks for ur response

start the car.. spray some water on your wires and your cap.. see if it bogs down.

edit: oops i thought i read when it rained. but it said nice day.

Well you got a mis-fire.. you can check the resistance of each of plug wire to see if its a plug (as well as check if its arcing by using water).. check your cap/rotor.. has your fuel filter been changing recently?

A misfire is normally caused by one or two things.. weak spark or lean conditions.

As well if its a wire or injector it may help if you remove each plug wire at a time.. when you remove each wire the motor should bog down.. if one cylinder bogs down less or doesn't even budge then you know the problem is with cylinder x.

Hey guys, I'm gonna revive this post here. It sounds like i have the exact same problem with my 95 civic, acceleration is jerky sometimes and i did notice it in warm weather. Everything on my civic is oem with no mods or anything. I've got this car recently used so im not sure when things have been changed.

Symptoms: sometimes accelerating from a dead stop, it'll will hesitate to kick into full acceleration. Also sometimes gliding from 60k/hr or so, and trying to accelerate from there this will happen again...let go of gas, step on it again...same thing. I would have to do this untill it gets to a certain speed and it will accelerate smoothly again.

I've already checked the wires and the resistance ranges from 8-11k, from what u guys are saying, it should be ok. Now, what exaclty is "arcing"? I'm tempted to try this but hesitant when i dont even know what im trying to see. I haven't tried changing the plugs yet but just in case its not the plugs i just wanted some other trouble shootiing options. Other than that, is there anyway to test the rotor w/o actually replacing it? If so, how? Someone had told me that it simply could be my tranny starting to fail on me but checking the tranny oil, it looks clean and in good shape. Anyone have any further insight? Thanks in advance!
