Cleaning throttle body question

???????????????? is it something that i should do and could i gain any power???????????/

It'll keep your throttle from sticking. It'd have to be pretty dirty to make a difference in power. I've never cleaned mine. :grimace:

OKIE DOKIE i ran my intake wide open b4 with out a fliter when i raced that SRT4 GRRRRRRRRRRR and i dk it would prolly help throttle response

When you go to sell the car, I hope any potential buyers haven't found this site! :roll:

SHHHHHHHHHHHHHHHHHHH

It won't ADD any power, but it won't hurt to do it. Best case senario is that it will restore lost power. But what helps restore lost throttle response better? TB cleaning or top engine clean?

im just gonna go with the throttle body clean sumtime this spring!!!

Me too. I'm gonna do that and top engine clean

hmmmm i dont really feel confident to do that im gonna jack a northstar V8 throttle body and throw that on der !!!!!!!!!!!!!!!!!!!! hahahah JJK

It's been done. N* TB will increase flow for sure, but not needed at this stage.

yah i have seen it on www.3800performance.com

wbodystore.com has a good deal on one and it is considered one of the better N* kits.

i've cleaned and pollished my TB and it helped restore lost power. all the carbon on the back of the buterfly and crap built up as far back as i could reach. it had never been done (i did it at 100k milles). top clean doesnt really get all the carbon off the TB so a removal and clean is needed if you want it super clean and running perfect.

has any of you ever heard of porting the throttle body?

its not really going to help unless you port the s/c too. you can buy them pre-ported from zzp (i think)

brianteel or animul

hmm i just was carousing on www.clubgp.com and found an article on porting the throttle body of course there was no write up

Hello,

I bought one of those aerosol cans of throttle body cleaner in Automotive store to spray it into the throttle body. However the can says not to spray it over MAF, so I removed it, disconnected it and started the car. At first it struggled alot to idle but I gave it some gas and it seemed to have stabilized.

My question is,

Is it OK to spray the cleaner into the throttle body without the MAF being there? Will the engine stall out?



PS. The directions on the can say to spray it sparingly over 10 second intervals. Spray the entire can.



THank you very much.

first off, welcome to the forum! i remember you from regalgs (unless someone else has your name)
the car will run rough w/out a MAF plugged in. which can did you get? the STP version if MAF safe. your best bet would be to just remove the TB and clean it manually. the gasket is only like $6 and the results will be 10x better than just spaying stuff past the butterfly valve onto the rotors.

Thank you very very much for such promt reply.
Yes, I am coming from RegalGS on a PM I received ;-)
Looks like you got everybody here.

I do not remember the brand exactly, but I do not think it is MAF safe anyways. I agree on doing the cleaning manually. I wish I had time for this procedure.

My car is acting up, so im trying to clean out sensors. I cleaned the Injectors, have new CPS, cleaned the IAC, have new fuel filter, tried different octaine gas and still have struggling throttle issues.

WHen I floor the gas, from around 1000-2000 rpm, I hear and feel the engine struggling reving the RPMS. But once its past 2000. they rev up quite fast. This happens in all gears and NEU and PARK.

I still cant figure out the problem. maybe you guys could help?

Here are some tech data Ive collected recently:

DIAGNOSTICS AT IDLE:

RPM (Idle)
In Park/NEU - 800-852
In DRIVE - 600-661 (Is it normal being lower than in Park?)

MAF (LB/A)
In Park/NEU - 0.67 - 0.68
In DRIVE - 0.58 - 0.60

ABSLT TPS (%)
0.0 at Idle

02S11 (V)
Constant jumps between 0.045 - 0.85



Thank you,
Ive been trying to resolve this issue for many months and still cannot understand what is cauing this. Help would be GREATLY appreciated.


THANK YOU THANK YOU THANK YOU!!!!

OH yea One more thing:

If I "abuse" the engine and keep floring it, despite the fact that it is having so much difficulties to rev up RPMs in the beginning, I get the following codes:

P1406 - EGR PINTLE POSITION CIRCUIT
AND CYLINDER MISFIRE (NO SPECIFIC ONE)

I'm assuming you have a scan tool of some sort. if you watch your TPS does it change smoothly as you get into the gas pedal? (can be checked with the engine off, key on)

have you cleaned the actually MAF sensor? how old are your plugs and wires?

Is you Riviera supercharged? If so you should not have used the Throttle Body cleaner as it will damage the coating on the supercharger rotors.

Hello,

Thank you for replies!!!!

My Rivvi is not SC.
I have not used the TB cleaner yet...
I will take the time to monitor the data while acceleration and will report soon!!!
Yes, I sprayed the MAF several times with the aerosol cleaner.
Wires were replaced last summer.
Plugs were replaced 2 yrs ago
Thank you very much for the consideration guys!!!

(Please excuse my tardiness)
