3.4 swap sputtering!!! HELP!!!!
ok guys so ive just completed my swap and it idles great!!! and drives great until about a 1/4 throttle when it starts to sputter and die ive done some research and it sounds like A DIRTY MAF which ive now cleaned TWICE!!!! i also thought it may be a bad fuel pressure regulator because when i pinch the return lines it revs just fine!!! i have no idea what to do next, help would be greatly appreciated!!!

yes it did. i bought a rolled 4runner and as soon as i got it home and charged the bat. it fired right up and went through all rpm ranges just fine.... but that was 3 months ago.
also when i crimp the return line she runs awesome. i just through a vice grip on the line and drove it up and down the block and it ran perfectly. ( could light up my 32's in 4th gear ) lol
so could it still be a tps???

ok i replaced the tps and it changes nothing... i went through all my wires for tps and maf and they all check out... so once again it comes back to fuel pressure... what is the best way to check and see if my fpr is bad???
