i was comming up from orlando to miami. and out of nowhere i lost power. the Car seemd to still be running. but if i gave it gas it just felt like it lost Spark on one of the Coil packs or it lost gas flow. this only seems to happen when it warms up.
things i did befor this were Basicly Run Seafoam into the vac line after it Cleard out it seemd to be fine.
Car idles Will speed up, but if you push it at all more then Half Accell it will Coke or somthing.
I really need help im stuck here in Miami till i can get an Ight idea of what this might be and how to fix it

also when i let off the gas it runs normaly.

 

Sounds like limp mode to me.... is your check engine light on when it loses power?
FYI- "limp mode" is a failsafe mode that the ECU goes into when it senses that something is wrong with the car, it won't let you go more than like 2500 rpms or something like that.... when it happens, try restarting the car and see if it stops. While that is NOT a permanent fix for the problem, it will get you home.

 

its an 88 GXL, lol there's no Check light.
i really donno what to do atm

 

Fuel filter, plugs, wires, how recent are they? Have you within maybe oh say the last year run out of gas to where the car stopped?

 

erm i almost Ran out of gas one time... it was cutting out sounding like it was running on one bank... but i got Fuel Befor it lost all of it.
Fuel Filter new, Plugs are somwhat old, Wires are fairly New.

 

check to see if the tps is connected - and you should also compression test it

 

check your spark plug wires- make sure they are all connected and snug

clogged fuel filter? might try bypassing your fuel filter with a piece of brass plumer's tube.

 

How recently did you almost run out of gas? That can kill your fuel pump, it can take anywhere from a few days to a few months, but it will do it on old fuel pumps pretty bad, expecially on an old car with alot of in tank sediment.

 

it just got a new Winebrow or wallburro Pump... its Whining like a .... somothing that whines. But its still pumping

 

Has it always whined like that since you got it new?

 

not at first, but it got louder as it got broke in.
Alot of people on here told me it was Normal.
Am i to be correctid?

 

the walboro is extreme overkill on a n/a. that could be part of yoru problem

 

to much Fuel Press?
wouldent it just get returnd to the Tank?

And if it being that, what would be a better Pump... that is not so damn loud and more reliable

 

well ive gone over what i could..... its 9:18PM and i gotta get back to orlando...
so.. wish me luck

 

Disconnect the battery for five minutes and reconnect. This will clear the computer memory and default it to base settings. This WILL NOT cure your problem, but may allow you to drive home, if indeen it is your computer going into limp mode.

 

it's an S4, ecu fixes do nothing to the S4 ECU. It's a dumb ecu that doesn't learn any new settings.

Your problem is purely mechanical.....what it is exactly, I can't say.

 

lololol, Well i got it narrowd down to Plugs wires and Fuel Pump... This all possibly Startid after the Walboro was installd

 

HAHAHHA. I like that one. So true!

How does your engine idle?
Does it start easy?
Does it rev up slow in neutral?

 

bro search for problems stock na's have had with high end fuel pumps, i'm almost sure thats your problem. the stock FPR may not be able to handle that pressure.

also check and see if you could have a clogged fuel line or possibly the pump itself clogged up

 

IT starts Right up Idle's a little Jumpy Mostly Slight Sputtering
Revs GREAT when Cold. When its hot or the Coils are hot it hits like 4-5 K and Sounds like it died. then idle's Back out.
I took out the Spark plugs today, they lookd kinda od.
All of them lookd the same Sept for the Buttem right.
the center was a little Burnd down.
The top of the plugs lookd Half White with Some ashy feeling Crud on them.
and the other half was Black and ashy.
