[scoopy03]

this post is regard to my first post http://www.automotiveforums.com/vbul...d.php?t=692294

Car was driven half hour before the scan was done.
Car was monitored for 5 min. Here are the results

Abslt tps % 0.4
Rpm 663-717 rpm keep changing like from 660s to 700s like every second
Calc Load 2.4%
Maf 0.49 - 0.51
MAP 10.3 - 10.6
Coolant 217
IAT 126
IGN Adv 19 - 21
IT FTRM1 -18
ST FTRM1 0.8 - 3.9

Please let me know if this results sound reasonable or anything is pointing out any possible problem that my car maybe be having. The fan comes on. The car was a little above the middle line so around like 235 when I scanned it.

What problem are you having with the car? Also your link is dead.

[scoopy03]

the fluctrating rpm's high coolant temperature. fans almost always on 5 minutes after starting the car and running it like up to the store regardless of the temperature outside. when i first got the car about 3 years ago it never had the guage in the middle it was always like around 190 not 220ish or 230 when the fans come on. plus on the intake it feels like u can cook an egg.

Sounds like a cooling problem. What maintence have you done to the cooling system.

only flushed out the radiator not a full flush

Perhaps too the LIM gasket is leaking? Does the bottom of the oil fill cap look like mayonase? Is there any seepage outside of the intakes?

I'd get a full flush before the dexcool starts to clog up your heatercore, thermostat/etc.

Actually, one of the great things about dexcool is that one of things it contributes is to not clog, and would not clog either/or. Try looking for a minor leak in the thermostat housing which is actually separate from the thermastat. I know, sounds crazy, but its the same design as the Grand Am set up.

I have a similar issue on my 99. The temp gets upward to 210-ish in town when it's around 75F.

Turns out the water pump isn't moving freely. Changing that this weekend and hopefully it'll be back to normal.
Also with it running (wear gloves because it can be hot) feel the hose on the driver side coming from the radiator.

After the thermostat opens up, if it feels kind of soft (there is air in the coolant system.) It's something like that
anyway. grab a socket and bleed the air out from the valve on top of water pump.
