I recently bought a mr2, 1991 Mr2 Turbo with a 93 engine and tranny swap, my second one. The car ran fine for a month or two but there was always a boost leak, which turned into a lack of blow-off in between some shifts...compressor surge scares me so i investigated, eventually i ended up attributing this to the TXS blow-off valve that looked like it was hanging on for dear life lol... I bought a USED trust BOV(recirc) to try and fix the problem, it did for a while, but still with a leak, I used the create-a-gasket and it fixed the vaccum leak problem... or so I thought, even now it still lopes liike a v8 ahha eventually shutting itself off around every other complete stop or 1st gear roll, basically whenever the clutch is fully in.
I used a different size hose, a little bit smaller, on the BOV this time, because the stock hose wasnt long enough.... but it is not weak enough to collapse so i didnt figure it would be a problem... But still the same problems are happening, i would say every other day, and it seems to be contigent upon each other, if the blow-off is working , then the car is lopeing at idle and shutting off, if the blow off isnt doing anything, not opening... but the car won't lope... Also, when it is working, it doesnt sound right, something sounds wrong with the BOV...
Another piece of info, my stock boost gauge has been going crazy since i bought the car, saying i am at full boost at 1500 in first, or half boost at idle...typical haha...
Any ideas??? Thanks to everyone in advance for you help and even if you dont know at least you got this far! thanks!
