My S8 Rx7 Spitters and stutters when i floor It! No Boost at all
Hey all. Have encountered a problem with my rx.
Just repluged the battery today to take her for a spin. First time i have disconnected the battery so it wouldnt die on me as I went on a 2 week holiday. Heated her up, started driving and all seemed fine under 2500revs. Went to floor it and all it did was spitter and splatter and stutter and was feeling like it was dying on me, so i eased off. Power seemed lumpy under 3ooorevs and stutters when full throttle.
Everything was fine 2 weeks ago. Only engine mods are airfilters and cat back exhaust. Stocko computer, turbos, intercooler, etc.
At first i originally thought dirty fuel/injectors, so i gave it a lil bit more only for it to only get worse. Had a quick check/lookover of engine bay, but nothing too obvious. Does not make boost at all.
Funny noise it makes is when i try to give a lil, then back off, it kinda makes a sound like when your turning off a vacum cleaner, a lil howling/vacum sound. I think possibly the stock Blow off valve opening????
I was think maybe fuel pump fault/computer fault???
Any suggestions?
Cheers

Also, it wont even go over 4-5000 revs. I was thinking intercooler pipe, but all seems good to me. One mate was saying to check sensors, as it is most likely electrical. Has this happened to anyone before?

c'mon guys need your help on this...
Car will only make 2 psi of boost and its a struggle to get over 4-5000revs. Have checked intercooler pipes...
Where can i locate the airfolw meter or map sensor line?
I'm thinking that i may have blown the secondary turbo, hence the air leak, hence the low boost, hence the spitter and stutter.....
need some help guys... what does a blown turbo feel like???
Cheers all.
