New DSM, some boost leak and other problems

[Raymos210]

Ps: Also the air/fuel gauge stays on all green lights which I think indicate that the car is running rich and the car's check engine light is on. The guy I bought it from said that the light is on because it has no cat.

well check the code its throwing and find out for sure then maybe we can help you

So the car as a 16g with a FMIC on stock fuel system?

Dude that car needs some serious fuel love.

But on a side now, it seems like you have gotten yourself a nice little starter DSM.

Hey thanks, I'm gonna get the code checked out by my mechanic prolly on tuesday. Also what do you mean by fuel love. What fuel mods do u think I should get?

[steviek]

like as a minimum 550cc's and a 190fp with maybe an safc then your good to like 22psi

My autometer gauge goes crazy going from lean to rich when my car is idle and also the idle fluctuates and then settles down around 1000. And this also stays "lean". Also my boost gauge stays on the "vac" side around "20" and when I rev it goes to "0." I definitely think theres something wrong lol.

Welcome to the DSM world, nice buy!

I'm goin to move this to the Problem Diagnosis subforum with a change in title, and leave a redirect here.

|IM going to guess that your a/f gauge is narrowband therefore rendering it useless. See the A/f thread in tech articles and writeups. Basically don't put any faith into that gauge its just for show reading voltage off your o2 sensor.

No fuel mods on a 16g, better keep the boost down, especially if you have nothing to monitor whats going on inside the engine.

[steviek]

also thats how a boost gauge should work... You won't make any boost in neutral. When you rev it you should go to 0 and when you at idle around 18hg is great. You should only make boost in gear unless you got a stutterbox... but you don't so don't worry bout it (link owners yes I know).

I havent raised the boost on the car yet...should I still buy the fuel mods eventhough I havent raised the boost at all?

I think you need to just sit down and do a bunch of reading and figure out exactly what you want out of the car first. That will make your decision easier and will help down the road if you do decide to upgrade. That "lightshow" A/F gauge is basically useless, it gives no accurate readings therefore has really nothing important to offer, it's just a nice lightshow. But you need to figure out what you want from the car before you go and buy a bunch of fuel mods.

[Raymos210]

Yea, I understand you. Right now all I want to do is get the car running the way it should. Later on I would like to tune the car and get it to push more horses out, but as of right now I just want the car to run with the pwer it should b putting down. By the way thanks for all you guys help, I'm still trying to learn more and more about these cars lol.

Well for starters I would go with a Walbro 190 (255 if you can find a cheap one), 550 injectors, and a SAFC. That should get you at a good starting point with that 16g you got and a little bit of headroom for some minor upgrades later.

Won't he need an FPR if he gets a 255 though? Might want to mention that.
