Doesn't idol right smokes out of the tailpipe

[m72steeda]

I have just added a Granitelli MAF I think it is 90mm calibrated for 30# injectors. I have also installed 30# FMS injectors. When i started the engine it is now just stumbling and will not accelerate at all. It also has alot of smoke coming out of the tailpipe. I think it is black so it seems like excess fuel.

Does anyone have a suggestion on what to do about this? I would greatly appreciate the help!!

My car is a 95 Mustang GT

How long did you let the car run???? How many miles did you put on it??

The computer likely needs to relearn the new setup......Give it at least 20-30 miles and see what happens.

put your mods in your sig so we can see what you have. Try reseting the cpu.

I onnly let it run for like a minute when I saw all the smoke and I turned it off. I tried again after a couple of changes but still the same. Are you saying that I should let it run for awhile even with all that smoke?

Answer

Found the issue

I called Granitelli and they said it is a defect and they are sending me a new sensor. So now I have to wait 4-5 days till I get the new one.

By disconnecting the MAS it would run just fine but it would idle high because it did not know what else to do.

I don't know what to say about Granitelli except there customer service and engineering really suck . The instructions are like 2 sentences long and say disconnect and reasemble the way you took it apart. It also does not adapt to any kind of filter system because they do not supply you with an adapter. And the connector does not lock together and they told me that they can not fix that for another couple of months. The person on the phone told me twist tie it on so it connects. I mean come on .
Oh an don't bother sending emails to them because it has been over a week and I still have not gotten a response from the 2 emails that I sent them.
