so what did i break now?

[Chuckie B]

Lastnight was on the highway and of course a new 5.0 Comes up next to me begging me to play...only can take so much before i give in...get in a nice pull and i get off at my exit....

stop at the light and the car starts idleing down n like its going to stall out. Lights are dimming etc. Thought way maybe i thru a belt but still have power stearing and still making boost... ...

I baby it to the next gas station and the cars driving acting fine...i park it and let it idle...cars does fine. For 20 Secs and then does the same idle issue....it was dark but i checked all the vac hoses n made sure everything looked good,fuse in the boost a pump is good...fuel pressure is fine untill obv it wants to stal n adds more fuel?

I turned it on n off multiple times after i contine to keep checking under the hood for hoses loose etc....and it idles fine for a good 30Sec-Min before it acts up...decide to baby it home(Cars driving fine,i let off the gas no studdering or stalling) I get home n let it idle in the driveway.....idles fine fore 5+ Mins???

Now im coconfused?...did something get a bad reading or? Going to look more after work in the daylight but just curious if anyone had any ideas?

Chuck...you need to stop beating the $hit out of your car!

....I'd start by putting a scanner on the car & check for codes!! ...also, since you purchased the car, YOU might want to consider having the tune checked!

Haha my few highway pulls every once in awile i dont think compares to ripping in down the track 6 Times in a day 0-120+ Getting traction!
Yes im going to sneak out of work a little early so i can have it scanned...id like to say its not the tune & Something else has changed bc its ran fine for. The 800Miles home and the other 800 Or so ive put on it here...but ive been planning on putting it on a dyno anyways so now might be the time! Wish me luck haha

Yeahh had a stupid issue like this with my old car with check engine lights tho...ended up being an 02 Sensor....hopefully a hose came lose and i just couldnt see it in the dark

FYI your power steering belt is on the inner belt.. only alt and blower are on the outer belt... if you blow an outer belt your battery light will come right on... I was first thinking your FRPP maybe blew the disk but if its ideals fine then perhaps your IAT'S were starting to get hot and the computer starts to pull timing... :idk: Might want to check the IC pump and make sure it has a good flow..

Haha see im new to these cobras...when i would throw the belt on my Kb 2V id lose everything.....

Frpp??? Yea like i said it would idle fine for 30Seconds n then start doing it...but when i got home it idled for 5Minutes and no surging or so stalling

And as for the computer pulling timing this is possible...good idea ill check the pump when i get home.

Thanks for the info!!

^^^ FRPS .... Fuel Rail Pressure Sensor!!!! ....I would think you'd kick a code!!

I blew off a boost hose that goes into throttle body and was doing what u describe. Was hard to tell it had come off with out tugging on each hose.

Good catch.. I'm getting older the mind is not like it used to be... :smash:

Check the plugs in it also try and notice if the idle kicks down and acts funny when the fan turns on could be pointing to an Alt on its way out.

What was wrong with your cobra did you figure it out?
