Thread: Problems after installing Walbro 255

The idle is fine, it just hesitates when im at like 2k+ when ever i give it gas it stumbles under accleration (daily driving) and under boost.

What tee are you refering too? I have the stock u12 intake pipe and stock hose going to the VC

What plugs are you running? Gap?

Bosch They are gapped to factory spec.

I know i need some NGK and a smaller gap

definitly some ngk spark plugs are worth investing in

I lowered the fuel pressure down to 44psi. Seems better. I gotta drive it more to notice more of a difference

when you go into boost any hesitation?

Change those plugs out! Definitely need something better than the bosch junks you got on there. Need to close down the gap too. I don't think that car would run very well at all in boost with factory gapped plugs, without an external ignition source.

^^ Told him that like 2 years ago. <-rob

a little still.



Remember the thread you posted in a while ago about "hey rob if you need help just become a vendor and get a big banner at the top the screen so everyone knows you need help" it was something close to that.

Edit. i found it lol







I am going to try and get some NGKs today

Well the very first thing you should do when you get your plugs, is gap them down to .030 or .028. Hell, just for ****s and grins, you should gap the Bosch cheapies you got on there now down to .030, and see what happens.
