Rechecked installation
I did find one electrical connection that wasnt made, it was not the MAF. I did go ahead and check all the connections at this point. It did start up and idle but still runs very rough, not quite as bad as before but certainly not good. I did stop by Toyota and got OEM...
The plugs that came out were not dual electrode and it had been running great until last Friday and it starting running really rough . Error coded P0303 and P0304
parts used

spark plugs - Autolite Iridium XP Spark Plug
Part #XP5224
Exact Fit for your 2002 Toyota 4Runner
Didn't gap plugs as they were supposed to be pre gapped at .044
I got a 02 SR5 4x4
I purchased a 2002 SR5 4x4 with 142,000 for 5k here in Kentucky recently. I absolutely love it. The dealer was going to wholesale it cause it was so trashed on the interior. I told them I was interested and they got that thing pristine!!
Happy hunting!!!!
