Hello everyone,
I recently bought a 2004 C5 Corvette with a LSX 376 and a Magnanuson TVS2300 SC. The previous owner had passed away and not much is known about it. I did a full tune up on it as it had been sitting for over a year - changed all fluids, filters, spark plugs (.40 gap), wires and replaced generic ebay coils with some MSD coils.
The issue I am having is a hesitation and stumbling around 1700rpm to 2400rpm. After that it drives just fine. Also the idle would randomly stay at 1500rpm for a little while then slowly come back down..
I can do a datalog (just got my hptuner) and post it or post a dump of the whole tune. Still playing around with the hptuner without doing anything dangerous or risky as a newbie lol.
