Help. Car is running like shit.

energiesource · September 13th, 2009, 12:46 AM

Hey so i did a cam install. started it up today. it starts. it kept dieing and almost dieing, im assuming that part is just because i dont have a tune, but i go to drive it and its so fucking jerky like i touch the gas and it fuckin jerks like im just learning to drive standard or something, anyone know what could be the problem? and if i can fix it just with my SF3 tuner?

BakerFX4 · September 13th, 2009, 12:52 AM

if your dead sure the timing is right then im going to guess that you DEFINITELY need a tune.

energiesource · September 13th, 2009, 12:56 AM

it idles fine, its when i start actually driving it.. i dunno what it is. im wondering if theres any like air fuel ratios i can change or what that would make it a bit more managable so i can drive it to a shop

BakerFX4 · September 13th, 2009, 01:00 AM

tow it... you prolly just need a tune bad. Think about it! that car is totally fucked from what that computer is trying to do.

yea u need a tune because right now your car still thinks it has the stock cams in it

<---Votes Tune.

jivepepper · September 13th, 2009, 03:35 AM

I could see a tune keeping it from running great or idle a little bad, but it shouldn't cause it to be as bad as you describe. I would check for vacuum leaks unplugged connectors like maf, crank position, and cam position sensors.

I changed my cams and drove it 220 miles to my tuners it ran pretty good even before my tune.

energiesource · September 13th, 2009, 05:18 AM

thanks jivepepper. it was the MAF plug. i also didnt notice that my jlt intake didnt use the stupid plug thats connected to that maf plug either. not sure what it is,

BakerFX4 · September 13th, 2009, 11:38 AM

i was thinking the same thing jive said. Yellow said his was driving pretty descent after his cam install. Glad you found it.

energiesource · September 13th, 2009, 01:27 PM

thats the connector for your air inlet temp sensor on a 2000, you need to transfer the sensor into your new cold air kit or it'll never run right.

takiller · September 13th, 2009, 03:12 PM

hey man what cam did you decide to go with?

pber13 · September 13th, 2009, 08:45 PM

what are the stats for the cam?

dannyboy281 · September 16th, 2009, 04:35 AM

did you end up using the same springs or did you upgrade also how much did the cams cost you

98stanger · September 16th, 2009, 06:38 PM

i know its the tune lol. when i put my stroker in before i put my break in tune in it wouldnt idle for shit and jerkes around. even with the break in tune it still jerks like a rabbit haha

suprajay79 · September 16th, 2009, 08:40 PM

Dammit, Jive, you beat me to it! I came across this post and read it, and then said to myself "MAF..." and then I scrolled down and saw you stole my thunder! Damn you!

Just playin Jive.

I have the same cams. I got them on sale for 500$ and the springs were another 200. Kelly(from modularspeed) says not to run stock springs with em. They aren't a crazy cam but they sound great and make good power.
