I bought the car from Jim expo.com. Yeah it seems like I got sold a turd but now it's a turd I have to fix haha. I checked both of those, the engine management system is an impul hi powerAZhitman wrote:...and so it begins.
Welcome aboard, J. Who did you import it through? Sounds like they sold you a turd.
What engine management system is it using? How did you check the MAF / TPS?
That may be true but at the same time we're not talking about a stock modern NA 4-banger, it's a 25-year old twin turbo I6 with a '90s era aftermarket ECU that was almost certainly tuned for higher octane gas. Bad gas would be an easy thing to rule out and much cheaper than getting a new ECU right off the bat. Either way, I think most people would agree he shouldn't be running the car on straight US pump gas until he can get it retuned and fix whatever ends up being the cause.AZhitman wrote:Those sound like pretty drastic symptoms for octane deficiency alone.
Maybe but I don't think it's a tune because when the check light is not on the car runs.perfect, not too lean, not too rich, just nice and smooth. It seems electrical to me. Trying to find a maf at the momentAZhitman wrote:Yeah, not knowing what kind of tune is on that ECU is a big no-no. Hell, he may have already done some damage.
Yeah that's whY I stopped messing with it, I'm going to replace a few sensors and try again. I'm going to the o2 sensors, and if that doesn't work, I'll try the maf if that doesn't work I'm going to have a good cryAZhitman wrote:Until you figure out what's going on, continuing to fire it up is likely doing damage. You don't really have any way of knowing if it's running lean or rich (unless you have a wideband). Did you measure voltage from the MAF, TPS, and CAS?
We have a FSM right here on the site with a full troubleshooting progression. There's no reason to keep beating on it and expecting something to change.
