wow, that is crazy. logic and the symptoms shown would lead one to believe that it would be a transmission problem.

glad to hear though that it was a somewhat simple fix.

as for MAF sensors going bad, i have been hearing more and more about the HKS Hybrid panel filter causing debris to enter after prolonged use. i am using one myself, but occasionally pop it open to see how it's doing. as soon the filter is spent, i am definitely going to get a WORKS drop-in filter. from the research i have been doing, they are the best. the only drawback is the price.

 

Maybe the previous guy over oiled the air filter and fouled up the MAF sensor...

 

That's what I'm assuming as well.

Still no problems with the car since the MAF change.

 

Well, I was driving around today, just out of the office to go get some lunch, and The car started these same symptoms again. Jerky shifts along with a service engine soon light. Taking the car to the dealer this afternoon to have it looked at. I've put about 2200 miles on the car since the MAF was replaced.

Maybe I'll get lucky and have this happen a couple more times so the lemon law can save me. I'm starting to get upset about this problem.

If it's the MAF sensor again, it doesn't make sense. I take ridiculously good care of that car. It never goes off road, it does not have an aftermarket air filter on it, it never sits outside overnight. Most of the summer it sits for a week at a time in my garage because I'm always riding my motorcycle.

Updates to come....

 

There may be a reason that the car was on the used car lot :-/

You've not had exceedingly good luck with it.

 

No doubt...

 

Wow that's really odd. I've had my RA for 9000 miles so far and nothing wrong with the tc-sst even with a lot of flogging.

Might be there's a leak somewhere and unfiltered air's getting pass the filter onto the MAF?

 

When you were driving and the clutches were slipping, you probably overheated the tranny, which probably gave you the "slow down" warning. And with an unknown history of the car, if the dealership doesn't replace the tranny, I would definately recommend replacing the tranny fluid. God knows what color it is, what condition its in, etc. Not saying that will solve your problem, but man, I bet you its filthy.

 

WORKS filter is great, but I also got the MAF code (P1235) last week - MAF problem.

 

Only had that happen one time, but that was also while it was slipping like a madman, and while I was taking the video. That was months ago. This most recent time, I didn't get that message.

 

So, I just had to throw a **** storm at the dealership. Lady from service calls me and says the car threw the P1235 code, and that they found modifications, and because of the modifications, they wouldn't cover the problem, and the warranty would be void. So, I drove down to the dealership and talked to a bunch of different people. All the people who I had told months ago, that I didn't mod the car, and that they sold me a modded car without disclosing that fact to me at the time of sale, which would have made me change my mind about the car. Needless to say, they backed down from their initial stance, and are going to cover whatever the problem is. I can honestly say I haven't done a single mod to this car, but the previous owner did put a TBE on it, but didn't remove the down pipe.

So, we'll see what they say the fix for the problem is, but it's the good ol P1235 code.

 

curious what you have in your car .. in terms of mods ..

weather is turning cooler ..

your maf's fine for now .. P1235 = maf plausibilty .. = invalid signal input .. which is saying the signal from the maf doesn't match the mapping ..

 

As far as mods that are STILL on the car, it's a downpipe, and lowering springs. Looks like the previous owner did a TBE, and took the cat back off.

I also find that statement interesting "MAF plausibility", because that doesn't necessarily mean it's the MAF. They checked the computer, and it looks as if it's never been flashed, as far as they can tell, so I don't think there's any ECU changes.

 

oh its the maf alright .. but it doesn't tell you if its gone bad ..

you don't need to be flashed to trigger this code .. any modifications that changes the way the engine breathes is likely to trigger this code ..

 

Indeed.
