Give me an email (admin@sssquid.com) and I'll get you setup for the right stuff!

thanks, ill be sure to do that this spring when my car comes out of storage.

IT FINALLY WORKS! I got a tune from sssquid tuning and it works absolutely amazing. I'm not sure what is going on with my trm tune Or what exactly ots actually tuned for but I would very highly recommend sssquid tuning. She finally opened up at full throttle. Didn't die when it was first started but yet still seems to run pretty rich. But she finally drives like a normal car

Probably was flooding the cylinders with fuel causing it to not spark, mine did the same, won't show on the wideband as it's not burning the fuel.

:up::up::up::up: Get me some AFR readings and I'll be more than happy to adjust fueling for you. The o2 feedback should cure with a little driving however.

one thing i noticed the other day was that when i rev it normally it backfires. but when i rev it up to higher rpms it won't. i don't know if that's anything significant. and it won't hold it's idle if the engine's cold, it will die 2 or 3 times and then finally stay idling.

I replaced the filter when this issue first started to happen. So it's got a brand new filter but I'll pull the filter and the pump to inspect the gas tank.

I put a gauge on and it was pumping just fine. I've looked inside the tank before when I was changing the fuel pump and didn't see anything but I guess it wouldn't hurt to check again.

The best thing to do is pull the filter. dump the inlet side into a glass jar. If it comes out like red clay then you've got a sediment issue. Of course this would also show on a FP test under driving conditions. Dwayne's car ran fine for miles until enough sediment clogged up injector #6.

It'd also be really helpful to be able to watch your fuel pressure when driving. You can always tape a gauge to your windshield :p

yeah I'd say check the gas tank - I had similar symptoms (m20b25) only experienced under load due to floating cancer in my tank.

[chuck90m3]

Nope not the fuel pump, mine is new with a new filter also.

[e-dirtym52]

Its not the fuel pump itself. I still have yet to test the voltage of it when the problem occurs due to it just snowed here so hopefully this week I can take it out real quick.

I recommend inspecting your fuel pump if you haven't already.
I had a similar thing happen to me on my swap. Symptoms were a motor that stumbled under WOT, often stalling -- was worse on right turns (which was the dead giveaway to a fuel problem). It was because the sock at the end of my (non OEM) high flow fuel pump came off, sloshing around in there and blocking the pickup under high load. Car ran fine otherwise. Sure was fun fishing that plastic piece of shit out of a 4" hole while breathing in all that carcinogenic fumes.
