Today I changed the dizzy cap and rotor and also cleaned the MAF and t-body with choke and carb cleaner (apparently a mistake)


Now, the car idles weird AND the TRAC off and CEL come on under 1500 RPM or so.


Did I seriously screw this thing up?

 

Did you make sure you plugged your MAF back in properly?

I'm fairly certain I did. Its one plug...lol.

I sprayed it down quite well and in the throttle body as well while the intake was off.

 

I don't have a working car now...lol

I squirted a ton of choke and brake cleaner into the throttle body and watched it brown up and run back out. Hopefully I'm referring right to the MAF (Right after the air filter box and before the intake pipe?) I also cleaned the first O2 sensor with carb cleaner. Everything is hooked up right so I think

Other than that all I did was remove the heat shield from the exhaust manifold to paint it black.

What happens now is that the car will sputter a few times and then drop to zero. Occasionally can get it to run if you floor it and let it rest after a few minutes but then under two grand or so it throws the CEL and TRAC off lights.

I'm stumped. And broke


EDIT: I searched about this and I read that the 1UZFE pre OBDII MAF from either the LS or SC400 will work with slight modification. I can get one from a salvage yard. WOuld that do the trick? I can't think of other parts that I knocked around

 

have to replace the MAF. ppl spray it, and alot of ppl say it throws CEL's and stuff...

Peace out

 

I think I'm going to have to.

I just hope the 400 one will work for me. At least for a while.

 

I just picked up an SC400 MAF at a junk yard. They said the engine was running when the car was wrecked and was only there because of the body damage.

Any advice to stick this sucker in?

 

Those are the exact symptoms of a bad MAF - been through several over the years.

As for SC400 to SC300 I have no idea. Didn't know it was possible. I would have spent the extra money and gotten an SC300 MAF.

Don't forget to reset your ECU

I've cleaned out my MAF a few times before I went with the MAP ECU. I use electric contact cleaner and have never messed it up.

The SC400 MAF will work. It's an upgrade for NA-T guys because it can read more airflow before it maxes out and works better with bigger injectors.

 

i was told that the air flow sensor is a laser read one, that's why the carb cleaner ****ed up the laser reading, causing it to run like *****, jus for future reference, peace mane

so if we want to clean it use electric contact cleaner? i should wait till i save up enough money to buy another one if i mess it up, lol.

peace out

 

Use electric contact cleaner and then let it sit and dry before you hook it back up. It dries pretty quickly but I've always done it before I went to bed.

 

Do you think its still usable?

I picked one up from an SC400 and swapped sensors, not the housing.


I will N-E-V-E-R own an SC400. That thing is such a PITA to work on. It took me probably a good 45 minutes to get out the MAF sensor and housing.


That is in comparison to the five minutes it takes for my 300.

Good grief...lol

 

Why did you swap it all? I believe you could've just plugged it in and put it in place of the SC300 one.
