CRC electric cleaner

[ptt]

Is it OK to spray (clean) the MAF element with CRC ELECTRIC CLENER or do you have to use a MAF specific cleaner?  Thanks.

I have both, but use the contact cleaner for harness's and the MAF cleaner for the MAF.

It won't hurt it.

Thanks for your replies.  I just replaced my coil pack and ICM.  The bracket holding the ICM was pretty clean nut the old coil was leaking down onto the radiator hose so it was time to replace it.  Upon starting the engine the idle was surging so I pullef the connector off the MAF and it normally idled.  MAF cleaning next...thus my original post.  Will post results.  Thanks all.

Did you disconnect the battery to replace the ICM? If so that might account for the rough idle. The ECM goes through a short learning process when first started after the battery has been disconnected. Just a guess...

I had the battery out and on a maintainer.  The engine stayed running after MAF was disconnected.  Bad MAF?

Please be aware that CRC makes two electrical cleaners and one is NOT safe to use on plastics (ask me how I know). Read the directions on the can carefully.

My cleaner is the plastic safe type.  So after spraying the MAF element there was no change...engine died after warming up from cold start.  Would not restart and remain running.  i waited for engine to completely cool and started back up.  I Unplugged the MAF and it continued to idle all the way thru warmup and never did die again.  So...is the MAF suspect?  This Reatta is the one that doesnt show complete letters and numerals when doing diagnostics.  I haven't been able to locate my OBD-I scanner to check it either.  I'm not sure I want to try to chance driving it to Autozone to see if they can scan it.  I'm wondering if they even carry OBD-I scanning capabilities anymore.  Anyone Know if they do?

Looks like you have three Reattas. Why don't you swap in a MAF sensor from a good running Reatta and see if there is a difference. Also be sure you have an "O" ring on the shaft of the MAF sensor.

New MAF seems to have fixed the stalling.  I recently put a new CRANK SENSOR on this Reatta and noticed that the HARMONIC BALANCER had a few small cracks in the rubber element.of it.  Not very big but there none the less.  Does the HB go bad all at once or will it last a little longer?  The last one I had go bad started to click at low RPM.

Replace the harmonic balancer ASAP. If it goes off axis,  it'll take out the crankshaft position sensor which will complicate your repair  (and make it more expensive). Such a failure will also leave you stranded, requiring a tow home or to a shop.
