what up guys need help. my acr experienced what i think to be a hiccup today it happened when my rpm's were around 4500 at full boost and the car seemed to be okay like it hiccuped and before i could get off the gas it was ok so it seemed but then i let off and it drove home fine but i did not floor it my plugs are gapped at .40. Can someone make sense of this¿

 

im gana help him cause it was kinda hard to understand.
He was at WOT and the car hesitated. Like he let off then got back on it again is what he ment by hiccup

 

sounds like you had some spark blow out...a smaller gap may fix this....it prob will...try .35 or .32

 

thanks guys will do, and thank you yellow ss you've been a big help.

 

holy **** .32 gap is way to close! i run NGK brr7e i think there one step colder not sure
and i gap them at .40 start up on cold mornings idle is funny but once the car is warm the car runs smooth all the way to 7 grand... i used to have hiccups all the time on the stock tune before stage kits

 

do a boost leak check... my friend with a stg II had the same problem... ended up his valve cover gasket was leaking, and a line came off his hard piping... also regap the plugs to .035 and try a colder plus... by the way are you running a WGA (waste gate actuator) if so check what boost your hitting...

 

WGA? maybe that's a coby term, are you tlaking about the bypass valve? or soemthing else??

 

waste gate actuator and its a turbop term my friend..../.. I work on a lot of SRT's... seen the same problem time and time again... (AGP one is the best) but if you have it set too high you can sometimes get spark blowout and get the hiccup and full throttle.

 

ya he did say ACR....SRT-4 ACR (american club racing)

 

yeah I know... but you can put a WGA in any srt-4 just controlled when the waste gate opens and lets you get more boost over stock... cheapest and best mod for an srt. beside the MBC or for the tech challenged... a manual boost controller. (I'm a member on the NYC srt club... don't own one but work on em)

 

Yeah, i saw that too. I was wondering how long before someone asked.

 

lol, sorry, I am well aware of what a waste gate is in a turbo application and also what ACR is, but you just said Stage 2, and I assumed balt, but apearently you meant SRT
Hell, ours bassically IS an internal wastegate.

I assumed he mean 'CAR' and it was just a typo.. i mean, this is a cobalt site!

PS) he DID mean cobalt, and the 'acr' was a typo

 

true.. but I help whoever needs within what I know.... there's more srts than cobalts around by me so we joined together to go rice hunting .... domestics demons baby...

 

alright bought ngkbr8e and i will gap at .35 and let you know what happens, however today i ran it and no hiccup however when i ran it today it was almost 20 degrees warmer than last night when it happened. so we will see.

 

nonon..the step colders are NGKBKR7E

not 8

 

i went to pep boys they gave me the wrong plugs i got ngk br8e and they didn't look right so i took it back and no-one in palm beach at any auto store has the brk7e so i ordered them tonight and will wait, but also i stripped one of the star key screws (just the top of the screw not the engine) on top of the spark plug cover and cannot get it off anyone know how to fix this problem
