Greetings! Long time lurker, finally took the plunge about two months ago. 2013 LR4, 80,000 miles. Have grown to like the vehicle even more than I ever expected. Daughter and wife have also, which was completely unexpected. Unfortunately, I am get a stumbling upon 3/4 acceleration only 6 weeks after purchasing. Light throttle and full throttle are generally fine. This is only during fairly heavy acceleration. Have taken it to two different shops, no codes. New air filters, cleaned MAF sensors, physically cleaned throttlebody plate to no avail. Both mechanics seem to think that this is carbon buildup on the valves. Have run two bottles of Techron through it, and one bottle of Liqui-Moly Valve cleaner (I have 11 more to go). Started running shell and Sunoco top-tier gas in it. Absolutely no change yet.
Do you all concur that this is likely? Both agreed that it won’t leave me stranded (for THIS issue, at least) but it’s maddening trying to solve this, obviously because there are no trouble codes.
Walnut blasting the valves has been recommended to me, but wanted to get your thoughts first.
Thank you.
