Rxxxxx7

Hey all. Have encountered a problem with my FD '99 rx7.

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, 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. only makes abouyt .2 bar boost.

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???

1: have checked intercooler pipes-all good
2: have checked with spare computer-all good
3: Where to next?

Im kinda thinking it may be the secondary turbo- hence the uneasy driving, low boost, boost leak, etc, etc...

what do you guys think?

Cheers
