When you say check fuel pressure. How do i check fuel pressure ? And any part that i need to change or adjust ?

They have a automatically regulated fuel pressure rail, the regulator is at the end of the fuel rail on the passenger side and releases fuel back to the tank to lower pressure. It has a little boost line to change fuel pressure depending on manifold pressure.

They are around $100 on ebay and only require a pair of circlip pliers to change. There is a valve to test pressure of on the rail with a black cap covering it, you need to get your hands on a suitable gauge to test though. It probably cheaper to just buy the reg then test equipment.

Don't guess and throw $100sss away.
I bought a T piece, and with some short pieces of fuel hose and extra clamps, install a cheap fuel pressure gauge and could leave it on.
Google or search this site, test procedure has been done to death by myself and others.

Lean or late timing.....

If the engine check light came on then it should have stored a code....

Okay ill start by changing the fuel reg and see how it goes from there. Can we install a rising rate fuel reg ones with a gauge thats on it already to our l67's ? And if so is there a write up been searching nothing came up.

You could but there is not a real need on std and mildly modified engines.

Hey guys just updating. Have replaced the fuel pressure regulator. Was a 5 min job on the l67 a breeze infact for once lol. Have replaced it a week or so ago just thought id drive it up and down to work to see if the problem does occur again before i posted a update on here. Car runs good now so if anyone has the symptoms i had look at FPR first. Id like to thank everyone for there help very much appricaited
