Check your MAF. Make sure its plugged in and the connector isn't lose.

 

[dsmrebel084]

It's plugged in and not loose

Whats your A/F ratios whats your spark plugs look like?

 

[dsmrebel084]

Idk the A/F ratio but I pulled the plugs n thy wer fouled out so I cleaned n regaped thm n put thm bac n tried 2 run the motor a few more times n pulled thm again n there not fouling out

Do you live in South County near Lemay? I see a white talon around there alot and may be able to help you out if I you live close.

 

[dsmrebel084]

I wish I leave n north county....I really need dome teachings by people who kno these cars

 

[Junkyardspecial]

Ah man there is a white N/A on my GF's street that stares at me everytime i go by. Where in Noco, florissant? My car will occasionally do this when its hot but it wont die, it just bogs a bit. I use copper plugs, It might be time to get new ones.

First off, can you give us a bit more background on you vehicle? Mods, maintenance, ect.
Next, have you done a boost leak test?

Edit:
(Double post fixed, sorry I'm on my crappy HTC hero.)

I had a problem with my front o2 sensor, it was hooked up incorrect. The car had no to very little power. When the car seems like it was about to die, i'll give it gas but it would die. Since im guessing you have'nt installed a new o2 sensor, it could be bad and need replacement.

I live n Spanish lake but rite now my car is not turbo'ed yet...I got the thing hella cheap n I got it running...once I got it running I did a full tune up on it and the only mods I hav is a cold air intake and a full exhaust

 

[skatershawn]

Sorry, says you have a turbo. Since that's out of the question, try a new o2 sensor, new wires and plugs, make sure its all firing correctly, and check for any possible vacuum leaks.
If all passes well, I would check fuel, change fuel filter,see if injectors are working properly, fuel pump is good, and see what you have from there.

I'm not telling to do all at once, just work your way down the list to slowly narrow the possibilities!

Good luck.

[ChiTownHussla]

sounds lik a fuel or ecu related issue

 

[awdmonster1904]

Check your coolant temp sensor

 

[dsmrebel084]

Ok...I changed everything..new o2 sensor wires injectors plugs but ### I also 4got 2 mention is tht I redid the whole fuel system. It has a fuel cell wit a 190 pump n afpr. And the problem started lik a week ago once I let the battery die on mii

 

[werx]

Have you replace the timing belt and/or tensioner?

 

[AlaskanDsm]

Check your coolant temp sensor

agreed! I had similar issues when the wires to the coolent temp sensor got busted off. I am not sure how the NT coolant temp housing looks but check anyways

 

[ChiTownHussla]

I am running without coolant temp sensor...np

 

[delta448]

Make sure the AFPR is set to the correct fuel pressure at idle with the vac line disconnected.

If that doesn't work, maybe you should put the stock non-turbo injectors back in.

 

[skatershawn]

Wait, you running 450s on a n/a untuned?

 

[dsmrebel084]

No I hav the stock 240s n I'm tryin 2 tube with the afpr I hav

 

[LandoAWD]

ENGLISH! Speak it...

 

[dsmrebel084]

Lol srry...I blame my phone. Darn HTC evo

 

[LandoAWD]

My phone would have put the "o" in "sorry".

No excuses. Don't expect help if you can't take the time to ask like an adult.
