If my ignition timing was off, Would i notice a lack of power? My tracker seems really underpowered. I just don't think its running right. I have to floor it to go anywhere. But if the ignition timing was off wouldn't it run pretty crapily? I don't know any help is appreciated. Thanks Andrew

Well I guess nobody has any input? ??? ??
-
Yes retarded timing can cause poor performance although ignition timing does not normally wear out of it's inital factory setting
It's more likely starving or constipated . If the air, fuel delivery or exhaust is restricted you will experience a signifigant power loss things to chect air filter fuel filter (normal maintance) catalytic converter and muffler.
There are other possible causes but these are the most comon
Hope that helps.

Possibly a duff 02 sensor, especially if you've been wading.

Yeah that does help, but i just did the air filter over the summer and the fuel filter last week. Also the head was done on the motor so I don't know if the timing was changed then. There is a ticking sound that comes from what sounds like the intake manifold at around 2000 to 2800 rpms. I initally thought it was a plug wire arching but I replaced the Plugs wires cap and rotor and it didn't stop....so It kind of leads me to believe that it is the timing. Any more input would be great. Andrew

If it was an o2 sensor wouldn't the check engine light come on? I don't know just wondering.

Not necessarily, they do age and they also suffer from contamination on the outside. If the head has been off then both the ignition and the valve timing could be out. The valve lash may also need readjusting.
-
Valve timing isn't out, I just did the timing belt last week. Also i have the 16 valve motor which is an interference motor therefor if the valve timing was out there would be even bigger problems. I had the head professionally rebuilt and if that is the problem im' going to be super pissed. So I guess its time to check the o2 sensor. Thanks
-
You could be a cam tooth off either direction and it would still run. Might even sound ok at an idle.
But if its the same before and after the belt was done. Then most likely you can count it out. Still might be worth a shot messing with the distributer.

stupid question of the day,
Where is the plug you have to put the jumper in so you can check the timing?
-
Not a stupid question. I haven't done it yet so I don't know either???
-
i think the ticking that you hear is the injector nin the throttle body. mine dose it too. lata stu
-
I have no idea. gonna do some work on it tomorrow. Gonna ohm the o2 sensor and see how that is. And work my way around from there.
-
so where is the plug?
-
What engine?
-
93 1.6L 8v
-
Its next to the right hand headlight You want to put a jumper on the two leads that are opposite where the clip is
-
had to bring this one back.
i have a '95 16v and this is one noisey motor, i've replaced the fuel filter, put in a K&N and replaced the entire exaust with Calmini exaust combo. and this thing ticks quite a bit.
i've owned 2 other track/kicks but both were 8v's and they were quiet as a mouse. The car runs absolutely awesome, no power loss or hesitation just the slight ticking noise i hear. Is light to moderate ticking noise a common trait of the 16V motors?
-
Speed, I emailed you a couple of scanned images from the Chilton's manual #66500.
You can check the O2 sensor heater with an ohmmeter. A good reading is about 10-15 ohms and it gets its power from the ECU. Do NOT check the O2 sensor itself with an ohmmeter. Check the sensor with the meter on DC voltage. The sensor puts out a voltage in the range of 0 VDC (very lean) to about 1 VDC (very rich). When cruising, the signal will tend to bounce around 450-600 millivolts.
If the oxygen sensor is bad, it won't set a CEL until the engine has been running about 15-20 minutes with a significantly bad sensor input. The sensor can be bad but the ECU will still think it's good. That's why it's a good idea to see what the sensor is doing by checking its actual output with a meter.
Don, y'all

The ticking is common with fuel injector intake arrangement. The injectors pulsing is a normal sound. You did not have that sound on a 8V because it is a TBI and the injectors are sealed under the air filter assy. Remove the air cleaner hat and you will hear the same ticking on the 8V also.
-
Thanks a lot. I'll have to look into that today. I was going to check the ignition timing today, but I guess I will check that first. The motor just doesn't seem to be running right. I wish I had something to compare to.
