try 93 octane or 91 octane for a while mine would cycle v4-v8 rapidly with 87 octane..
with 87 i barely get 18.5/18.5 with AFM rapid cycle (it would cause jerking/shutter)
make sure you get the fuel from a good source like chevron/texaco or mobil/exxon
the mileage should increase as well I average 22 in the city and 25-26 on the highway with 91oct so the extra cost is actually cheaper to get it..
0.173 per mile with 87 octane $3.199
0.1545/0.131 per mile with 91octane $3.399 according to the math it's cheaper to run on 91 octane
i had bad luck with shell givin 87 at the 91 pump
the switch from v4-v8 or v8 to v4 is seamless and undetectable...
you will need to drain the whole tank then fill it with 91 remember not to fill it up if the fuel pump is hot, it might cause thermal damage(thermal shock) and seize the pump.
i would check the Air filter as well probably clogged up.. since it;s happening on a DFCO
event.. basically it just pumps air threw the engine when it happens
to remove the air filter i would remove the whole air box much easier to deal with and will save a bunch of time .. it also is easier to seat the filter correctly.
if you try and remove the top cover with it installed it's such a pain (very very tight spaces with the risk of damaging the radiator hoses etc..)
i can take the air box off in 5min(total time is like 10min at the most) instead of trying to struggle to get the 4 star screws off with the air box installed this will take about 20-30min to do if you leave it installed in the suv.. since you gotta be careful with the High voltage cables and radiator hoses and seating the air filter correctly is also a slow process
