Another thing...My 'Teg has never thrown any code...engine light has never come on. Wonder if I should check it. How would I check it?

Your CEL should come on. To check the code, look under the glove box for a big green harness. Beside it is a smaller blue one, with 2 holes. Bend a paper clip so that you can stick both ends in both holes. Turn the battery on and read the long flashes followed by short flashes. It'll repeat itself, so you'll just have to figure out the pattern.

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
67 Catalyst low efficiency. (same as P0420)
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Evaporative Emission Control System insufficient purge flow

Replace the fuel filter yourself!!! $75 for labor is way too much, and you can do it yourself. It's pretty easy man. That's the first thing I did when I bought my car.

Dirty fuel filters usually cause horrible gas consumption. And yes, your thermostat is stuck open. Replace that too. It's a PITA to replace the thermostat though, but definitely doable.

Replace your spark plugs too.

Here's how to replace your fuel filter:

I can't find any articles on how to replace the thermostat, but to put it simply, follow your lower radiator hose all the way to the block and see where it ends. That's the thermostat. Be sure to drain your coolant first.

All right...replaced cap and rotor...nada. Pulled plugs...HoLY CRaP!!! The gap was so wide my gap tool couldn't measure it! Probably twice what it should be. F**king mechanics...got lazy and had the last tune up done. Replaced the plugs with platinum autolites and took her for a spin. That's where all that get up and go went. Still a little sputtering on take off though. Leads me to believe that I'm loosing juice somewhere. Wires maybe? Think I'll try those next. Trouble is I can't drop a grip on them cuz I'm moving to Santa Cruz next month. Any suggestions for the most bang for your buck with plug wires?

Thanks for all the info Dom. I'll try and run the codes tomorrow and I'll post the results.

If your CEL doesn't come on, you're not throwing a code.

As for plugs and wires, I went with stock plugs and stock wires. Reason being the stock plugs are already pre-gapped to factory specs. Less headache.

Autolite platinums are shitty, do yourself a favor and put the NGK's in it.

Grab some NGK plugs and wires. NGK > *

MSD makes good wires too.

Sorry it took so long to post my results...holidays, working a s**tload, etc. Replaced the plug wires and voila, all better. More guts than I've felt in a long time. Still doesn't explain the low engine temps, but those are gone now too. Maybe the plug was shorting out on the block (though there wasn't any exposed wire) and messing up a sensor or something. Dunno.

Anyway...thanks for all the help guys. Really appreciate it!
