now when i get on the gas all the way...its very "bogy" like its running realy rich.

but since its a new car and im former ls1 owner..i dont knwo how to check to know if its REALY running rich...and if it is how would i change it? and how would i change while makeing sure i dont run lean?

any help would kick ass guys thanks

the best way to check is to go to a dyno with a wideband A/F gauge and check it that way. I bought my 5.0 and it already had a fuel gauge on it so im not sure if there is a place on your FPR to add a gauge. But even if you go to a dyno you can get your pressure right, and your a/f right so you know your not too rich or lean, and you can also see what you are putting down.

wouldent that cost like $500 ? or would they no consider that a tune when just adjusting the A/F?

ok well check the fuel pressure. it seems to be ok, around 38-42 psi.

anything else it could be?

you should pull your MAF sensor and check to see if it is clogged with dirt, that was my problem. if it is clogged, electrical cleaner should clean it with some q-tips, but be careful, dont want to pay another 100 for that part.

and dont forget to check the plug wires and the bolts on the egr valve. thats what caused mine to bog

 

[stockstang23]

lets see here..tires plus suggested i do Cap,Rotor, and wires they did a diagnostic test and determinded that to be the problem...they told me something was hitting 1.2 Volts, and that when they sprayed water on something th car nearly dies.

anyway ill order the wires and rotor and **** tommrow and do that my self.

But do you guys agrea that this COULD be the problem?

 

[stockstang23]

ups for good mesure.

damn where i live there is a dyno that does 4 pulls for 40 bucks with a wideband. Where are you from?

sounds like a dirty or bad MAF to me.Good Luck

You would be hard pressed to run rich with a stock puter in a 94-95 (sans Cobras, which came with a nice tune). I would be lookin elsewhere - and it sounds like a good tune up is in order. SHould you choose to do it yourself, you will find ample assistance in here and learn a bit about the car.

Good luck.
