hey everyone im new here and this is my first toyota...... i so far have fix the code 52..... and though that would solve my issue.... but i still have a problem.... ok here we go....at idle or driving it occurs the RPM doesn't exceed 2000, it will run then cut off "fuel" (i assume) then when it returns to 1000 or 900 RPMs it will run then at 2000 cut out and so on so fourth...... would u know what would be going on...... would it be fuel related problem....? please help don't want to work very hard at this if its an EZ fix..... THANKS FOR YOUR TIME GOOD LICK ON YOUR PROJECT/DAILYS

P.S. No DTC... AKA (check engine light)
