Hi,
I have an E cam in the car I just bought and there are a couple things that are bugging me.
1. Upon startup it idles really low, like its gonna stall, then it goes up to about 1000 like it tries to keep the car running. After that it goes back down and that goes back and forth for a few minutes.
2. Does this cam normally have a rough idle?
3. Car is running really rich (it needs a tune and an exhaust leak fixed). Anything that would help this? It has a 70mm TB and 24lb injectors.

Don't waste money on a tune with mild bolt ons.
What you need is to adjust your idle by messing with the screw on the throttle body.
Clean your black and white connectors and check your vacuum connections as well.
And yes an E-cam has a slight lope.

Next time it does it pump your brake pedal (at idle) if it balances out its prolly a vacum routing issue, but in the end these cars have a mind of their own. What computer is in the car? What I mean by vacum routing is to many hoses off one vacum tree.

is it a h/c/i setup? is you maf set for those 24lbs? do you got the stock fuel reg? if you got a aftermarket one ,rent a fuelgauge or by one so you can adjust it.
I never got a tune but never had your kinda problem. On my h/c/i setup i had a custom grind that was way more lobe than the e303. I will tell you ,it would surge just when i start it or when i came to a stop, i would just rev it once and it would set at normal idle. My has an e303 on his setup, it had a brand new granitali maf from summit and he idle was shit . got a Cnl maf and solved it
Some Tuners dont even want to wrench on cars or want you to come in with a bad idle problem like that. Get the basic tune you need, Timing,fuel, idle ok, no codes poping up, Then get a chip/tune with no hassle [ April 13, 2007, 05:18 AM: Message edited by: Eddie510- ]

The car is a stick with a Tremec 3550 in it. After the car is warm it stops, and it has quite a lope.
The only other thing I have noticed when I take off slowly, it has a slight stutter when barely giving it gas. After I give it more gas it comes right out of it.

Mods so far:
GT40 Heads & Intake, 70mm TB with spacer, 24lb injectors, E Cam.
Paperwork does not show anything about a different MAF so I dont know if that has been changed. It does not have a CAI, but does have a K&N with the regular setup.
My plan is to take it to Apex and have a different catback put on and fix some leaks in the exhaust. Im hopin to get it tuned then.

If You have 24 # injector's then You have to have an aftermarket mass. I had the same issues with My E cam and did what Eddie 510 did, which was change the mass air meter and it fixed My problem like night and day. E cam is notorius for this shit. My recommendation is to try drilling the hole in the throttle body blade and if that does'nt work try to borrow a friend's meter that is calibrated for 24's & NA, then if that does'nt work throw that E cam in the garbage .
