[Captain-Obvious™]

every turbo honda I see at commerce backfires at least three times...

check plugs, cap, rotor, motor mount, axles.

backfire makes me think ignition issue, but if you had a mount going then the motor torqued hard enough it could've busted the mount that was already bad.

[jap_racer1]

new plugs new rotor button and cap mounts r original so im guessinng mounts it runs fine only backfired then now it just vibrates when i get near certain rpms other than that it runs fine??

[scttydb411]

if it vibrates at certain rpm then it's probably mount or axle related since it happens at a certain rpm.

[jap_racer1]

yeah the motor is sitting low on the driver side cv axle boot is like 1/2 cm. from the frame!!

so the main question is, what did it run even backing out of it

[jap_racer1]

i ran 14.2 shitty run if it wasnt backfiring and i didnt let out i would have run under 13 which is still slow as hell

well i figured out the complete problem today!!

being lazy me i let a shop change my upper driver side mount well they only put one bolt into the side of the block and there was so much tork it rip it off the block and took a good chunk out of my block so i got screwed on that end!! so now theres only two bolts in that mount!! shitty as hell!!

[FasTech]

Simple: Its falling apart! LOL j/k

[jap_racer1]

alright i got it rideable will fix moreo tommorow!!

[patrick4588]

so only 2 bolts holding the mount onto the engine?

[Decepticon™]

check the the half shaft. IDK but i had a similar problem and i bought a new half and the vibration is gone. But idk im just throwing that out there maybe it could help....

[jap_racer1]

yes only two bolts!!

[turbob20]

see if a plug wire may have popped off! that would explain the back fires and the vibration. also could be a stressed axel seperation..

this is to the person trying to tell me that a wire came loose all the sudden when i figured this out like 2 months ago as that redneck guy says

heres your sign?

[turbob20]

well help yourself next time and dont ask for help when your too sorry to even work on your own POS! letting some other guy work on your shit is like letting some other guy screw your girl...DIY...
