i installed all the stuff ,long tubes y pipe, new plugs,plug wires ,throttle body etc,by first the cars strong with stock tune ,but after 1 hour the car smells super,super rich, the car is also failing at idle ,also at high rpms what do you think ?is because of the after cats O2 sensors ,?MAf?Fuel filter clogged?also forgot that i deleter EGR but is no programed!

thx guys for help

 

Umm dude you need to get that tuned. with all those mods theres no way in hell that stock tuning can work. call Ion at madz28.com of check out pcm4less. both are great but im partial to Ion. he has great customer service and has done several cars that are almost exactly the same as yours.

 

thx for help,yeah i will do it tune as soon as its posible,the rare thing is that when i first drive the car ther car felt good,but after 3 hours ran very horrible,hell i even feel slower than stock.

thx man for help

 

maybe thats open and closed loop.. hinting that a tune is necessary

 

well you prolly fouled the plugs. if its puffing black smoke when your on the gas then those plugs wont last long. dont drive it, send the PCM to Ion and put new plugs in it.

 

yeah ,i will get tune as soon as it possible,i will no drive it again,without tune,i though the Fuel Filter was clogged or something,i will change it because i think the mechanic didnt changed it.

 

fuel filters are cheep and might as well change that.

I would NOT drive the car before getting it tuned.

The computer will be freaking out and dumping WAY to much fuel. If you are locky, you just replace the O2's and a new set of plugs and be dione with it. If you drive it very long, you will destroy the cylinder hone and pretty much "wet sand" the cylinders to the point the rings will never seal and the car will never run. Once the oil is contaminated with gas, the engine has to try and lubricate with this oil and main/rod bearing problems and piston/pin gaulling problems are right aroind the corner.

You REALLY need to get a tune before it is too late.

 

First, Lloyd and Ion's work are the best!!!! I have a LE2 WS6 and a bolt on 97SS both have mad z tunes and super happy with both cars and the WS6 is a rocket! Just need a 12 bolt! And in case you haven't noticed both are quick to help when you need it!!!!!!!!!!!!!!

 

thx a lot lloyd,i will do it the tune in monday,the problem is that i need to drive like 200miles to take it at the tuner,i will change oil and new plugs ,will i have a problem runing 200 miles with new oil and without tune?

thx for the info lloyd

 

With that kind of work, I would not drive it without a tune.

 

yeah,i know,i will no drive it after the tune is ready,

 

Get it towed to the tuner.

 

Yeah or just get a program that will let you drive it around. Ion, PCM4Less can help you with this. DONT DRIVE IT THERE!!!!

If you have a laptop and the tuning software I can send you my tune with my LE2 heads/GM847. At least it will be a lot closer.

 

Im confused as to why he's running rich though (unless he upgraded the injectors too, which I didn't see any mention of)

Assuming the fuel system is still sotck, the pcm should be able to acommodate the upgrades via fuel trims while he is cruising in close-loop non-PE. While he is in PE, if anything the car should be leaning out with all of the extra breathing ability.
