Stock 99 runs like crap below 3000rpm
 

Does it in all situations. Hot. Cold. Light throttle. Wot.

No CELs.

Above 3000 it is totally happy.

By runs like crap i mean consistently misses and stumbles.

Please help me fix my daily.

check timing?

did you put gas in it? if that one gauge on the left points at the E then there is your problem...

Spark plug wires? Although when my car used to cook mine, it would only stumble as it revved passed a certain rpm, usually between 3000-4000rpm. Worth a shot, we all know you like throwing money at your car.

Its funny because this sounds kinda like my problem but mine was 2000-2500 rpm. But my problem was anything above 50kpa load between 2k-2.5k and i was running E85 that had stayed there for a week without being touched. A member on miatanet said it was E85 going bad... problem disappeared halfway through the new tank.

You need to throw more turbo at it...that and a sawzall.

U gays rnt helping.

I am thinking it is due to some VVICSTS bullshi. All vac lines liok ok though. Opinins?

Vics dont do shi t at 3k rpm as far as drivability goes buu.

Coil packs?

Unplug whatever we're calling the intake air sensor and see if it behaves differently. I recently had a chaffed wire on my daily and had a similar symptom. I'm guessing it's a spark relate problem.

Why would it only misfire at low rpm though?

I will try unpluggin ait sensa

maybe 3k is the switchpoint for CL/OL and a bad sensor is causing it to freak out in CL?

Wouldnt this throw a CEL though?

Have you hooked up an OBDII scanner to watch what is going on with everything while this is happening?

I have a bluetooth OBDII adapter that I use with the app "Torque" on my phone and it allows me to monitor everything that is going on.

WTF is this OBDII scanner thing. Seriously, I have never heard of it.

I guess I can get one loaned from autozone or something? Or no?...

Yes, Vatozone will help you.

The cheap OBDII scanners just hook to the OBDII port and read codes, the expensive ones can read all the data that the ECU outputs. I bought bluetooth OBDII adapter for my pickup truck. I then use https://play.google.com/store/apps/details?id=org.prowl.torque&hl=en app on my phone as an interface for the adapter.

Droid only app?

I'm not a droid plebe.

i ball out with my iPhone 4s s for u iz suckaz

Torque is droid only.

Except your iPhone 4s has shitty blue tooth api's so developing blue tooth apps is next to impossible. So they are not exactly baller.

There might be other OBDII software for the iphone, I have never looked and have no desire to.
