hey whats up guys, you might remember my threads about my TPS and what not i've replaced the TPS, TPS harness and even the IAC motor but the car's idle still bounces i'm thinking its a vaccum leak. however i noticed today that while i was on the throttle the car would bog down and the wideband would go blank it did this a couple of times its the first time its done this any ideas? o yea another thing to when the idle bounces my lights flicker?

 

belt slipping?

 

would the serp. belt be responible for that tho it squeels when it gets wet but i didn't think anything of it

 

do you have an aftermarket cd player? my friends protege' had the same problems and when he took it in for a diagnoses they told him that he had some wires crossed on his head unit that were causing a short in the electrical system.... its a long shot, but possible...

 

no i still have the stock radio in but i did put in a sub [&:]

 

Unless you have the sub on when it's happening and are playing music very loudly it shouldn't have anything to do with it.

 

anyone think it could be a bad ground? bc the lights flicker when the idle bounces and the voltage meter on my s-afc goes crazy

 

I guess it could be. Check the battery terminals and see if they are loose. Maybe it's your batt or alternator?

 

ok heres a update. while i was getting my oil change yesterday at my buddies shop he threw in the obd scanner to check out my check engine light and my car threw 9 codes [&:]i'll list them all.

1. P0033 - turbocharger bypass valve circuit open
2. p0172B - bank 1 system too rich
3. P0253 - turbo wastegate solenoid A
4. P0507 - idle air control system RPMs higher than expected
5. P1105 - Mtc. or Mfc (i can't read this guys hand writing) controlled air/ fuel metering
6. P1188 - same as number 5
7. P1697 - Mfc. controlled comp. output circuit
8. P1854 - transmission
9. P2074 - M.A.P. / M.A.M (MAF) throttle position correlation at high load

can anyone explain these to me b/c i feel like my car is in a huge world of hurt especially that transmission code why would that turn on? i know some of these will be gone b/c the cars not tuned yet and its running rich as hell but can someone sum these up for me plz.

 

Oh snap! Was your car doing this before you put the Neo in? My buddy had a Neo installed and it caused all sorts of problems. Car would barely run! Could be throwing off your MAP sensor (code P2074) which would have an adverse effect on the way your car calculates everything causing the other codes...
