I have a 2002 z no mods really.. When I punch it off the start it misses and sputters. And acts like it has know power when I punch it while driving and will die sometimes.. I'm lost and not really sure what's wrong if you need anymore info ask and I'll give you all I can i just know it's getting warm and I need my car lol

SES light? Codes? Last time the MAF was cleaned?

[pajeff02]

Have you done any work on the car lately?

Like Smittro said, good idea to clean the MAF with some CRC Spray MAF cleaner that you can get at just about any parts store. Also, take a look at the inside of your throttle body while you have the MAF off as it may also need cleaned and inspect your PCV hose connection on the passenger side of the throttle body.

Have you checked your fuel pressure at the fuel rails?

[Coydawg6]

Yes ses light is on.. I have not cleaned the maf in a year and the codes that come up are maf, front O2, and to lean bank 1 and 2.. And yes it has plenty of fuel pressure lol I did check that

[pajeff02]

What was your pressure at the rail? Did you check it under load or just at idle?

[Coydawg6]

I don't remember cause that was the first thing I checked lol but I do remember that it was normal

Hm good pressure, lean bank 1-2..

You have 2 front 02's

Clean your MAF, then clear the codes and see what happens.. imo

I ment to say front sensors... I'm on my iPhone for the first time.. And also let's mention that it has a 170,000 miles on it haha

ahha. If you're still on factory 02's it's possible they need replaced..

[Coydawg6]

They have been replaced within 25000 miles

[Smittro]

They have been replaced within 25000 miles

I think we just narrowed it down then..

Nooooooooooooooooo! Stick with the stock unit.

have you checked for vacuum leaks? Start with the pcv hose where it bends to go into the intake. That hose likes to crack on the backside of the bend. How ( and what rpm) does the car idle? What was the number of the MAF code?
