Temperamental Power.

Best way I can put it...


I've noticed that sometimes the car will pull harder than a previous run. I know that there are alot of varibles with this... but I figured I post up about it, to see if anyone else has had simliar "issues".

My guess, it's an A/F "problem". Guess I could give the MAF a cleaning, but I dont think it needs it, OTH it could'nt hurt.

Yeah, I have that problem at times as well.... temperamental.....

Is this according to your butt dyno? Is it significant?

How old is your fuel pump? What about your fuel filter? Cleaning your MAF certainly won't hurt either.

Or maybe your butt dyno needs to be recalibrated? j/k

 

[SASHO91]

Yeah, could be my butt dyno is all messed up. I've been tuning my buddies 400hp GSX... so that might have messed with it..

Fuel pump is not too old, and is a 190LPH unit. Fuel filter is not even 3k old. I have yet to clean the MAF, but the last time I did it was maybe 2 months ago ( i am running a high flow[low filtration] filter though). The A/F gauge shows nothing wrong though.

Its weird... as sometimes she will pull hard to 120 and so on. but other times, she kinda just pulls decently up there... Maybe i'll go grab a new ECT sensor, when I pick up some MAF cleaner...

Sometimes my car will pull ******* the jesus gear... Sometimes it seems I am in fourth.
He did a good run last week with that modded 1984 350cu Z28

ive noticed this too... i think sometimes im missing... i have no oil in the cyllinders, but i think one of my plug wires is farked up.... it ususally only happens "under load" ive never had much luck getting my sho past 130... it seems to just hit a wall... maybe i should change out my plugs/wires..

 

[SASHO91]

Maybe i'll pick up some new wires... These are about 5 years old... but they are Motorcraft though.
