My wideband will hit 10.0 (only after 30 minutes) of driving. when this happens i Will get a sputter and hesitation before it Will go anywhere.

I have no CEL on, I think it's the MAP which is located on the back of my fast 102.

There is no easy way to change it so I was hoping for some pointers or tips/tricks on getting back there.

thanks in advance guys

I think the map may be covered in oil and that why the car will run for 30 miutes(until more oil works it's way up on the map)??

If this is the case I will need a catch can (probably a mighty mouse)

Does that sound like it could be the case?

stevieturbo

Not really, why not try and diagnose the problem instead of just taking wild guesses ?

ws6turbo

Like all boosted ls motors without a catch can,The intake is pretty oily. And with enough oily mist on the map it could sure malfunction. That's why I guess the map. This is where I'm starting.

What else could be giving me a rich condition 30-45 min after driving,and then after sitting for couple hours drives great again?could it be a o2?

stevieturbo

It could be many problems, least likely the map sensor.

Just get some form of scan tool and read live data and you'll see if the map sensor or any other sensors are reading strange.

ws6turbo

Ok thanks, I'm having the car retuned soon here so I'm trying to get everything straight..

I wish I could fit my big *** hands behind the intake and just remove the map.

stevieturbo

That would be a waste of time when it is so easy to test as I said. And doesnt matter what size your hands are.

ws6turbo

Right that is easier, I just need to drive the car until it starts going lean right? It won't tell me anything before then since the CEL is off correct?

stevieturbo

I'll repeat the above.

You need to review live sensor data to see if there is anything strange with the readings that may be causing an issue.

Given there are multiple sensors, it could be any one causing the problem, or more than one.

CEL or lack of really doesnt tell you much unfortunately.

ws6turbo

Alright cool, thanks for the response. I'm gonna mess around with it later today.

ws6turbo

I'm hoping it's not the map. I'd rather crawl under the car and switch a o2!. Thanks again

ws6turbo

Thanks Stevie!
I was way off, so after watching the live data, I knew my sensors were ALL good and started elsewhere.

Worked my way down the fuel system from the motor back and had no consistent pressure.I switched the relays on the primary and secondary pump, it started and ran great, so there was my problem.... a bad pump(which was brand new) guess a 6an line is too small for dual 340s, lol.

Good stuff.
