:eek I did my 30K Maintenance last night and my check engine light came on right after I replaced my spark Plugs. I drove the truck after the engine oil and Tranny Fluid were replaced and everything was fine. One I drove back, took the spark plugs out once everything was put back together my check engine light turned on. Could I have done something wrong. I re-checked all the sparkplug wires and the two hoeses I disconected in order to get to them and everything was ok. Can someone Please tell me what could be wrong. Also as I drove this morning onto the freeway once i pressed the gas to get to 65 the engine seemed to cut out/or die, but once i let the gas go a little it drove fine.

YOu need to gap your spark plugs to .043. I think you are having misfires due to improper gap.

 

[thanhnp]

How can you gap if theyhave the two electrodes (or whatever they are called) at the tip. What tool do I use?

You gap from the tip of the prong to the electrode for each prong.

 

[thanhnp]

It there a special tool for those type of plugs? I have used the type that you just slide between the prong and the electrode. Can these be used to gap these plugs?

No special tool.

No special tool, but the wire type of gauges are the most accurate.

 

[thanhnp]

Ok. Would I now have to buy new plugs? Am thinking cause the miss fire, would those plugs be fugged up?

 

[vlubber]

I think you may have another problem besides a gap issue. I pulled the dealer installed plugs (that I provided since the truck has the URD fuel kit) and found them to be gapped in the low thirties.

But I was not getting an engine check light. Just uneveness.

So in the case of a 3.4, the gap itself did not trigger the light. I would regap to .043 or .044 and also make sure the connections are solid. Regapping to .044 made a dramatic difference in smoothness. Also, like Gadget says, make sure you tighten the little caps on the tops of the plugs.

Why are you changing plugs at 30k anyway? That seems too soon.

First things first---We need to know what code you threw. Do you know? If not, get the code read before you randomly start changing things around. Let us know what the code is.

Where can I get a Code Reader. I know Auto Zone rents them for older cars. Does anyone know if one is available for 2002 Tacos in the San Jose/Fremont Area?

 

[TRDOLMAN]

Are you in Fremont? If so, I have one.

Dave

 

[thanhnp]

I work in Fremont near the Auto Mall.

 

[TRDOLMAN]

You are only a couple of miles from me. I will send you a PM with my phone number.

Hello!! Is anybody home??

But I was not getting an engine check light. Just uneveness.

So in the case of a 3.4, the gap itself did not trigger the light.

I would get the CEL blinking when my plugs were not gapped properly. I read somewhere that was the misfire indication. It was not a hard check engine light that would stay on. In fact the light would blink for a few miles and then go off. When I got home I would check it with the code reader and it didn't read any problem code. The light blinked on 3 different occations, but after I re-gapped them it never came back. However my gap was on the higher side rather than the lower side like yours.

 

[thanhnp]

I dont even know where the plugs are gapped at...

If you got the plugs from your dealer, then they should be gapped already- Doesn't hurt to check though, but all mine were when I did it.

Did you remove the ground on the left side of the block to get the plugs? I didn't put that back when I did it, and threw a CEL...

 

[thanhnp]

I just removed the Harness connected to each coil before I took out the Bolt that holds it. The plugs I got are the Densos that are listed on the manual. Got htem from Auto Zone though.
