Have a 03 silverado, been havin some problems. In the last year or 2 its died 2 or 3 times when steering wheel is cranked all the way, sometimes the idle rpms are real low like 200 to 400rpm and it doesnt have the "go" near like it used to, iv done routine maintenance on everything, trucks a 4.8 with only 110k miles 4l60e bone stock, reason im complaining is cuz I wanna take a break from my 5.3 s10 swap and I wanna do some basic bolt ons to this, gears, headers, cai maybe a 75 shot and a rel good tune
