Have a little of a head ache with my mr2 and need some advice from people who know stuff about it. i know a newbie in mr2, but never the less. I have a 91 mr2 with greddy turbo kit. ( turbocharger, inter-cooler, piping). Once when i was driving one of the turbo couplers came off. i put it back on and weird stuff began to happen. Car doesnt accelerate smoothly now, i get to 2500rpms and car begins to choke a little and feels like it doesnt have power to boost any further, it jerks. However giving it more gas would eventually break though that point at about 3000rpms and you cant feel the power back where it should be.
Between 2500rps and 3000rpms this is whats happening. i hear weird noise as in hose somewhere where the air intake is at either leaking or i dono what is up but it makes a flapping rubber noise like a weird fart or something, also the air mass flow sensor it makes like a metal to metal click sound just once, like it would get stuck or something.
so i checked all the couplers and the air intake, mass flow sensor is ok, gate moves nothing is blocking it. couplers are tight and doesnt seem like any of them are ripped or leaking. i do have a small exhaust leak after down pipe..can that me the problem?? changed all of my vacuum hoses to silicone ones.
also my VTV valve where the blow off broke so i ordered a new one and waiting on it but can that mess the boost so much???
my fuel to air mixture is too rich as well, at least thats what the gauge shows.
so any ideas???heed help!!!
thanks!!
