Warranty on used/tuned car w/ engine light?
This may be a little long, but I appreciate any help or advice I can get.
I got a '10 R/T Classic (auto) from a GM dealership -- they got it at auction. Sold to me with about 23 mos left on bumper to bumper and 47 mos on powertrain from Chrysler.
The car has corsa exhaust and a direct connection intake, but everything else seems original. I'm convinced that it's been tuned though, b/c it shifts hard, sounds great, isn't sluggish at all -- and I took it to the track and got a 13.65. It's a little shaky when sitting at lights, but it's not missing, it's just a little rumble.
On Saturday morning the engine light came on. I thought it was getting extra shaky when I'd let off the brake or let the car roll up in traffic -- it would lurch almost.
I took it to Advance and the guy hooked it up and FREAKED OUT. Told me it was throwing all these mod codes -- timing has been advanced, crankshaft this, camshaft that, wouldn't write anything down for me, but didn't tell me anything was WRONG, just that mods and permanent changes were showing.
He told me I cannot ever take it to Chrysler, my warranty is voided, I have to find a high performance place that understands the car, and I could be doing major engine damage by driving it.
It was running relatively fine, so I drove it. First I unplugged the battery, and for a while the engine light was off. The next time it came on, the ESP BAS and car w/ squiggly tire marks lights came on. ECO will not kick in/turn on, and cruise wouldn't work.
I filled it with gas and after that cruise worked fine. I tried not to really get into it or anything, but it just feels more sluggish already.
I guess my questions are:
1. Have I already possibly reset a tune that may have been on the car?
2. Does tuning/advancing timing void warranties? If so what might I be able to go back to the GM dealer with? They sold me a car with a warranty, and I haven't touched it. They should have been able to catch those codes.
3. If I take it to the dealer and nothing is wrong or they can turn the light off, are they automatically going to change the computer? Do they have to ask me first?
4. I'm trying to read the other threads on the ESP lights, but I haven't seen anything about ECO not coming on. What could be causing that?
Thanks for all of your help!
