new intake manifold gasket

[herrjimbo]

just had one installed. runs pretty good. took care of the idle problem. now my question.

will the ecu adapt to the lack of a vacuum leak? or should i reset the ecu so that it relearns?
the reason i ask is, deep down i'm afraid if i reset the ecu, it won't run as well as it does now. (after a month of idle problems, and $375 later, i'm pretty happy).

if it ain't broken don't fix it

It may have been reset already.

When I did repairs like that I usually disconnect the battery to make sure the engine would not turn over or get shocked while doing the repair.

$375 to install a manifold gasket?
what kind of car was this?

You ask because it was so cheap right???

98 mazda 626. no, new maf $90, used iac $60. the rest was for the gasket replacement.

they didn't disconnect the battery. all my radio presets as well as the clock remained untouched. i highly doubt they would know where the ecu is to disconnect.

so, i got one answer to my question. "if it ain't broke, don't fix it".

anyone else like to comment on "resetting ecu after replacing intake manifold gasket?"

i would not bother, imo "resetting ecu" is kind of overused, everyone says do it, but the ecu is always continuously adjusting anyways.

that's probably the best bet. i'm just a wee bit concerned that the ecu will "remember" when it was running like crap, if you know what i mean.

well, i got over my fears and reset the ecu. huge difference. when idling, the steering wheel has absolutely no jitters. smooth as silk. there is a tiny bit of jitter in the stick, but i'll be putting in new bushings on the tranny end when it gets warmer. did the shifter bushings last summer.
