Lagging issue question

[SmashedGlass]

88 spfi wagon, which appears to do the following....

 

I've noticed that until the Sube is fully warmed up (after about 12 minutes run time, needle on temp a little below half way) I tend to get a bit of a stumble or gutlessness between 2k-3k on the tach. After she's warm though, she runs absolutely great (for all of the 90hp in her).

 

So far I've checked the temp switch and sensor leads and connectors, as well as cleaned them as I read something somewhere about that possibly causing an issue; install clean air filter; and checked and properly gapped my plugs.

What I haven't yet done are fuel filter, clean the MAF, clean the IAC (she idles fine, don't think necessary), or clean the TPS.

 

Any ideas or tips?

Hmmm. After some digging around on here it seems...........

I've been driving it like my old 200SX, which is to say

LIKE A GRANNY lol. I didn't realize that you pretty much rev the

piss out of the N/A EA's, and I've been lugging it with shifts around

the 3k-3.5k mark. Will start romping the bejeebus out of it with shifts

much higher and see how she likes it.

my 90' OHC loyale is a little hesitant when its cold also, but if i need to get out of the way or get up to speed, i run it all the way to 5,500rpm and it does just fine. but if i want good gas mileage 3k shifts do just fine.:-p cant do any fast driving latley cause of ice and snow, but with 4wd theres fun to be had:brow:

 

Cheers.
