Well, the weather is getting cooler and I noticed when I start off in the morning, I get hesitation every time I switch gears - bogging when I step on the accelerator after the gear switch. This goes away in a couple of minutes, I presume after the car has wormed up some.

Is this normal? Thanks.

 

I have noticed this also over the past few weeks. My RX7 did the same thing the few times I drove it this time of year... So, I expect it is simply an issue of the car being cold...

 

Same here

 

same with me, must be the cold weather.... because half way down my road its fine...

 

Haven't noticed bogging or anything, but it hasn't gotten that cold yet.

You guys aren't hammering on the car before the oil and coolant are upto temp, are you? I wait at least until the coolant is in the normal range. I let the car idle for 20-30 seconds, then I take it easy and don't go wot or above 3500 rpm or so until everything is warmed up.

My Audi A4 1.8T had an oil temp gauge, and I could see that it would take much longer for the oil to get into "normal" range vs the coolant.

Is the bogging happening with WOT and at what rpm?

Thanks,

normal

 

same with my OZ, i was just about to make a post about this. I dunno but after i drive for about 5 minutes it gets better then 10 minutes it gets perfect.

 

Gotta let everything warm up before it's "normal" operation time. That includes drivetrain (tranny, clutch, etc.), engine, coolant (dependant on engine of course), oil, everything. Cars just don't like the cold!

 

"...You guys aren't hammering on the car before the oil and coolant are upto temp, are you?.."

Nope, just normal get up and go. If it is this hesitant now, I shudder to think what it'll be like when it really gets cold...

If it's normal, I guess I'll have to get used to warming the car up a bit before heading out.

A follow-up question - properly tuned A/F ratio should cure this to a great degree, no?

 

I also noticed that when its cold, warm car is idling closer to 950, while it was at 850 consistently when it was warm outside. Anyone else seeing this?

 

Does mitsu list driving this car below freezing as against operating procedures? I was wondering how the Evo's woudl fare through the winter, if this can be confirmed true.

 

Cold engines always idle higher, usually more like 200-400rpm higher than standard warm idle speed.

Mister2zx3, I can't imagine that's the case. All cars perform/act/seem different when it's cold, it's just the nature of contraction/expansion among joined parts and build clearances.
