new here to the forum awsomee site guys
well here is my problem i own a 91 mr2 N/A
i ended up gettin a jdm intake manifold and 15lb injectors well i put everything on and it wouldnt work i changed the fuel rail and blocked the egr valve that didnt work so i went back to the stock injectors and stock manifold and its still blogging
it runs fine but as soon as i give it some gas it blogs down i changed the spark plugs checked the disturbertor and adjusted the timing even re-adjusted the tps sensor and still nothing still blogging down after i give it some gas
it will go up to 2,000 rpms even 3,000rpms sometimes
what could be the reason please help thanks call me at 2709918950 i would really appreciate it thanks

So it's idling okay just bogging when you get on the gas?

91mr2ky · 03-05-2009, 04:41 PM

Have you checked your O2 sensor? If that's faulty it can create that symptom.

91mr2ky · 03-05-2009, 05:43 PM

replaced the o2 sensor stil not better

Gairloch · 03-05-2009, 06:11 PM

It wasn't bogging before you made the mods, right?

What's left that you modified and haven't replaced with the original stuff?

91mr2ky · 03-05-2009, 07:18 PM

it ran perfectly fine before
i returned everything back to stock like it was before

Gairloch · 03-06-2009, 12:48 AM

Something is still different then. Have you triple checked to make sure everything is where it's supposed to be?

91mr2ky · 03-06-2009, 11:40 AM

we put the stock injectors back on the stock manifold and we hooked everything back up like it was before
even when we had the jdm intake and the 15lb injectors it did the same thing but before we put the bigger injectors and jdm manifold it ran fine didnt bog down or anything
miter have to take evrything back out and start all over

Inspect your spark plugs wires before wasting money. i had simler problem with my mr2 & after i changed my spark plug wires my MK 2 ran like a dream.one of the metal sleeves in side one of the spark plug wires was loose.

91mr2ky · 03-07-2009, 04:37 AM

aha havent checked that yet i got spare wire in my garage i give it a try thanks

91mr2ky · 03-24-2009, 02:01 PM

ok checked all the spark plugs wires and stuff still nothing
the mechanic said it mite be the fuel pump idk
but i took the injectors out and rechecked everything and everything seemed fine
it runs really good but bogs down soon as i give it some throttle
