Car lacks power!

ChRis98GT · January 28th, 2010, 08:09 PM

Hey Guys,

Another thing is happening...

Recently I changed the intake manifold.

It ran fine for a week, now the car hesitates once in a while when I accelerate. It even does it at idle.
Its not throwing any codes or wasting any more gas. It just lags power when I really need it.

Any ideas why it's doing that?

-Thanks

does it hesitate when you stomp on it or when your just driving regularly?

sharkbait · January 28th, 2010, 08:15 PM

Make sure everythings tight. See if something came lose over the past week and is causeing a vacum leak. Running lean will cause you hesitation.

ChRis98GT · January 28th, 2010, 08:18 PM

it hesitates when im driving normal, but then it goes away. After a few minutes it comes back...

Ill recheck everything again sharkbait. Hopefully its something small...

wannabeimportkiller · January 28th, 2010, 08:23 PM

I was going to say the same thing, just check and see if everything is tight and what not.

it would amaze you how much vibration goes on. I always have to go back over my stuff. I normally set an hour a side a month and go over my stuff

Steelsoldi3r · January 28th, 2010, 08:57 PM

yea recheck everything

CobraPhoenix · January 29th, 2010, 10:44 PM

sounds like a vacuum leak, if it turns out not to be that it could be an ignition issue

ChRis98GT · February 4th, 2010, 04:32 PM

FOUND THE PROBLEM! YAY!!!!!!!!!!!!!!

Coolant was leaking into #4 spark plug. Im changing the hose and clamps so it stops the damn water!

Cleared out water from #4 plug, Runs smoooooth as butter once again!

Same Here!

Its a Drug i tell you...

sharkbait · February 5th, 2010, 07:29 AM

It seriously is. I wish cars just came with a knob that you could turn to make them faster.

With numbers that were like 12 11 10 9 8 7 6 all the way down to 4.

And those could be your quarter mile times. Save you the whole modding and driver mod proccess =P

Thumbie · February 5th, 2010, 06:59 PM

but then why would you ever have it on not the highest setting. its like the supercars with sport mode and stuff. I would always have it in sport mode haha

ChRis98GT · February 5th, 2010, 07:55 PM

sounded similar, but I fixed it and now its running GOOOOOOOOOOOOOOOOOOOOOOODDD!!! Sorry got carried away...

I would on nice days, but when the weather's bad out I absolutely love traction control...hell some of those supercars are difficult to control on perfectly dry pavement with the traction control turned off.

tc wasnt an option in 96. wish i couldve had it back when i first bought the car. my tires wouldnt be so bald :/

98FireyGT! · February 7th, 2010, 01:54 AM

Neither of my cars have TC, the mustang or the Jeep. The jeep is 4WD though which helps.

I found out about TC in my parents expedition though...that car is probably the nicest thing I've ever driven, fully loaded eddie bower package. Heated seats ftmfw.

Thumbie · February 7th, 2010, 06:27 AM

yeah sometimes having a luxurious interior is nice.....too bad it adds weight. a seperate DD is sometimesteh best option.
