sr starts but wont stay running

[sloanslovia13]

OK so here is The deal. I have a stock blacktop with a front mount and exhaust. Did The swap 2 weeks ago and the car ran great for two weeks. All the sudden it started hesitating in 5th gear. It would start to bog out the catch all of the sudden. Long story short, I had it towed home Saturday because it wont even hold an idle. Any help would be appreciated.



Things I've changed an checked
Tps new
Fuel filter and pump new walbro255
Coil packs an plugs
All vacuum lines and ic clamps no leaks
Ignitor is new

I don't have much time, its my daily.

check the MAF

Check the ecu for codes, that could give you some insite possibly

Also as stated above check the MAF

im thinking its your mafs also, mine did some crazy things when i had problems. try cleaning it and also check to make sure you didnt somehow suck something across it and bend one of the wires

check for vacuum leaks. perhaps the little screw that hold the throttle plate open has loosened and fallen out. that may explain your idle problem.
