i did a stupid thing when i was bored.

i have a g35x.

i took off the stock pleneum to see how hard it was to take off becasue i am thinking about doing that mod next (the kinetix one). after taking it off i put it back on without any problems. after i reconnected the throttle body before reconnecting the ztube i had my friend turn the car on a rev it so i can see the butterfly valve open and close. the car made some weired sounds, bogged out and then went dead. note: mass airflow sensor was disconnected. after the car died i reconnected the ztube and restarted the car.

when the car is at idle it sounds like its going to die and if i dont give it a little gas it does die. when i put it in drive it continues to boggle and when i floor it, it takes bout 5 seconds to begin to rev up and the when it does rev it it is noticibly slower. once i get the rpms up and it reaches 3rd gear it seems like its okay, but still sounds wrong and seems a little slower.

i reset the ecu becasue the check engine light, e-brake light, and slip light were all on. looked like christmas on my dashboard. i did it through the petal method. took me about 20 attempts but eventually got the check engine light to flash and now its not on any more. didn't help anything.

the car fumes also smell strong of gas and rotten eggs. thought it could be running too rich.

car sounds like **** now and i have no idea what i did.

someone that knows alot about cars, or has anyidea what it could be please help.


p.s. when i took the car on a main road to see if i could still drive it tomorrow to the shop, a wrx with an exhuast tried to race me and even with my broke *** car i still managed to beat him. should have killed him though. made me laugh casue i know the kid and hes a loser.

thanks, billy

 

When your reset your MIL with the pedal method, you simply cleared the trouble codes. It's likely that they will light up again since it sounds like something's still not running right. Maybe you just left an air-leak somewhere?

If your MIL trips again, use a code reader or Consult II to read what the problem is.

 

Make sure you installed the MAF in the correct direction.

 

I would say you have an air leak. The MAF thinks your getting a certain amount of air so it gives a certain amount of fuel. But if you have extra air coming in, it will run like **** and most likely stall. Either that, or you damaged your MAF sensor and it isnt relaying info to the ecu and your car is running like ****. If all else fails, take it to the dealer with everything intake-wise turned back to stock.

 

Hey I think its cause you took you engine cover off.

I think everyone has a pretty good take on this. Most likely you have a air leak somewhere or your MAF is damaged/installed incorrectly. Make sure you installed everything back correctly. And if you can get an OBD II reader to read your Error Code. One time I was taking the MAF off of my old '91 Camry. When I tried unhooking the sensor I damaged it. The symptoms upon start up where exaclty as you stated. All the dash lights came on, the idle was real rough, the car was running real rich, smelled strongly of gas and rotten eggs, etc. Got a OBD I reader which told me it was the MAF. If you have a damaged MAF that will cost you at least $350+. An expensive lesson to learn.

 

Mr. Bill,

There are many different hoses going in and out of the plenum. Are you sure you got all the hoses going to the right connector?... It would create major problems if they were miswired so to speak.

If you were luck enough for it to run it would smell like hell.

 

Same thing happened to me when I installed my plenum. I spent hrs checking hoses and tightening bolts. Turns out the was my MFS. I had to disconnect it to move the intake and forgot to plug it back in
