Wondering if anyone's had to change their spark plugs yet, I've been tuned for 13k miles, and they might need to be changed not sure yet though. Anybody knooooow?

 

i havnt herd of any problems but im
sub'd

 

ive changed mine out and im at 24k but i had problem w/ misfires

 

Yeah it did something strange this morning, so i might have it looked at tomorrow, but I just want someone knowledgeable to inform everybody.

See mine has misfired a couple times I believe, it made a couple looooooooooooooooooooooooooud ass pops, I haven't gotten the plugs thoroughly looked at yet though. Today floored in 2nd gear it wouldn't hold boost, and it felt weird, tried it again and it was fine. This is on a new tune also.

 

GM's reccomends replacement at 100k miles

 

You can take them out and check for fouling. I also had misfire and hesitation issues but that was due to a crappy tune from a local shop.

 

Well I'm not near 100k miles lol I don't think I got a crappy tune either it's from someone very smart on here but unfortunately I can't do any logging because my friend's cable isn't working properly. Time to take it out for a spin and see if it does it again.

 

anybody have problems after tune when 1-2 NLS'ing. it like bogs or something for a second. Like itll go to 6k shift, then to like 4k or whatever, and itll sit there for a second and the car will go BRRRRRRR and then it will accelerate. its not tire spin, its like a weird bogging thing that only happened after tune. My buddies who got tuned at the same place has the same problem. It tends to hurt my 1/4 mile times. It only happens sometimes but when im on the track and pushing it real hard and shifting quick

 

K well did two nice 2nd gear and two 3rd gear pulls, it was juuuuust perfectly fine, almost lost the steering wheel lol...hmm I dunno maybe my car is just pms'ing. I suppose I'll get the plugs looked at anyway.

 

My tune torque steers like a mother doesnt it.

 

Lol yes it does.

 

These cars eat plugs.

I have had to replace them a few times, usually every 5 thousand miles.

I will start to knock when I know it is time, if I wait a long time it will misfire, then it will act like a two step if I wait too long

 

So you're saying I should get them looked at then? lol

 

I think he is saying yes deffinately. These cars do tend to burn out plugs quickly. I guess it is a combination of iridium plugs and the tremendous heat this DI motor produces.

 

All righty then willlllllllll do!

 

Yep, exact same thing happened when I got tuned at a local shop. It ended up being knock during the 1-2 NLS...It pulled timing like crazy. Mine was due to a fuel spike during shifts...Once I leaned up the AFR it was good, I didn't have to ease up on timing at all.

 

Run nothing but the stock plugs.



I forget the part number off the top of my head, but they come gapped already too(ACDelcos) so you could change them yourself super easily.

Seriously Rissa...don't try anything else but the stock plugs...you'll have a car that won't rev past 4k

 

Lol oh I know that much at least Anyone know which ones they are exactly in case I need to buy new ones? For some reason search never works right for me!

 

I think they are like 6 bucks a piece

 

All right sweet! Car is getting a make over today and possibly new spark plugs. This bitch better be happy.

 

Glad to see this! Where was your lambda PE set and what is it at now?

 

The AC Delco part number is 41-108 . The plugs should last you 100,000 miles unless something or somebody has changed the engine's calibrations DRASTICALLY, or you have internal parts problems. If you're not getting a CEL I wouldn't worry about plugs.

 

17000 miles, 15000 which are on the BSR tune (yes, i know, its not as aggressive as other tunes out there) still running strong on original plugs.
