car won't idle after cam swap
i just installed the tourquer v2 camshaft in my 02 camaro and now the car won't idle. Is this normal? I have'nt got a tune yet This is probably the prob. but I just want to make sure. it is a auto and I have'nt put my stall in yet.

This morning when I crunk my car it ran smooth with no prob. no SES light or anything. And I let it run for bout 10 minutes. Now later on this evening I tried cranking and it wont even idle now and my car shakes violently, and I have a SES light. Gonna put my stall in this weekend. What do you guys think

No it will not idle in neutral, pretty sure it's not my o2 sensors , because I changed those out 3000 miles ago. Just seems kinda weird that it would run this morning and then 5 hours later it won't.

The computer has to learn the new cam. And a tune is a MUST. My friend just put a cam in his 99 Vette.... we let it run for a bit so the computer learned it, and tuned it 3 days later. Runs perfect. Good luck

Just got one ? on that. if I drill out the hole in my TB I know this will allow more in thus causing it to idle higher. So when I get a tune is my car gonna idle higher than normal or is that something required after a cam swap? Normal is a 550-600 rpm and that's where I want it to stay because I love the lope and sound at that level?

I just put the same cam in my car and it idled ok. It was fine on cold start, but hot starts were a little tough. It would take about 30 seconds of me babying it for it to find idle. After my tune, car drives perfect. Good daily driver cam btw.
I didn't drill out the TB. Just drive it straight to the tuner and you will be fine.

you need to put that stall in before you get tuned that way you dont have to waste time going back a second time.
and yeah get a tune. the reason why it idles on a cols start fine is cus the air is more dense and fills the cylinders... once it starts geting warmer the air gets less dense and the engine becomes less efficient (hence the lope, the cylinders are stealing air from one another because there is not enough air for all of them)
now, install that stall and make an appointment ahead of time. a good tuner is always booked.
