Hey its my first time on and I need advice. My 96 tahoe,275k,is acting up. I may have to take it in but thought I'd check here first. 3 weeks ago it started stuttering when accelerating up hills. Runs fine otherwise, though it had a hard time starting after a grocery stop the other day.
I changed the rotor and cap, fuel and air filters, and put in some injector cleaner. Wires are fairly new. A friend checked the computer for codes, nothing came up. About a year ago the code came up rear oxygen sensor. Ignored it cause it ran fine. I picked one up today but can't free up the old one.
What's the next step in the process? Thanks for any input.
