Engine Problems + CEL (interesting)

Hey guys,

Well, my engine kind of hesitates on heavy acceleration once in a while... it all started a few weeks ago. I kind of ignored it, but now I'm having some problems. Under heavy acceleration (when I floor the gas pedal), my engine seems to get stuck at different rpms (at random) and hesitates to go anywhere, kind of like I have a rev limiter all over my rpm range. It sounds like I'm hitting some limiter too.

Here's an example lol:

Normal engine under acceleration: Vrooooooooooooooooooooom
My engine under acceleration: Vrooooom-m-m-m-m-ooooom

And now finally, it's been getting worse and my CEL started blinking and then just stayed on.

Could it be the spark plugs? I don't know if those have ever been changed... What could it be that's causing this?

Thanks guys,

Igor

yes it could... i had similar symptoms when i had a bad spark plug cable.

the cable leaked electric power to the engine block and when i floored it it hesetates and sometimes misfires with a popping sound from the exhaust.

check the spark plugs and the wires too.

That is exactly what's happening... will do thanks

get the CEL scanned to be sure of what it is.

I had these same symptoms with a bad Crank Position Sensor and Cam Position Sensor.

I will get the CEL scanned tomorrow. As the spark plugs go, where can I get some performance ones, anybody has a link?

Thanks

There was a guy selling NGK Iridiums for the Lanos for 24.99. They would be my performance plugs of choice.

But if it is Spark Plugs, then it would still come up with something other than that, cause there's no censor there, correct?

eh... bosche platinum4's are like 5 dollars a piece at autozone or advance or napa or o'riely or pepboys or where-ever... best value

the iridiums are good plugs (either type) but they aren't worth the price (in my opinion)

$25 dollars

I hope thats for a set of four.

I really don't belive in the performance spark plug thing..... matching heat range and gap is more important in my opinion.

When it comes right down to it copper is still the best conductor available.

Here is a table showing conductivity.....in microohm-cm

Aluminum 2.655
Copper 1.678
Gold 2.24
Silver 1.586
Platinum 10.5
Iridium 4.7

As you can see.....only silver beats copper.... and copper is more than six times better than Platinum

Sure Platinum and Iridium don't corrode like copper but I'd rather replace the plug more often with the money I saved.

Copper is ductile which means it can take some abuse.... Platinum and Iridium electrodes can be easily damaged during a misfire.

Anyways...... it's just my opinion..... take it or leave it.

Yeah, it was for a set of four

. I agree with you about the plugs. I run basic, bottom of the line NGK's and have never had a single problem with the spark plug. I used to run Champion spark plugs from Wal-Mart, and even they ran fine. I believe that I've only changed the plugs on my car like 3 times and have always put in basic quality plugs. So far so good.

Does ACDelco make good spark plug wires? Anybody know?

Thanks

i used to run Champion on my car then switched to NGK and they were fine... now i am on Denso but i am not that sure of what i feel about them... i wanna go back to NGK.

well yesterday I bought NGK plugs and ACDelco wires... will see how they perform...

Interesting... I did a small burn out in first (the front of the car was sort of jumping) and the check engine light turned off. I shut the car off, and turned it back on, and the light comes of for a sec (when starting a car) and then comes off... just like it used to.
I'm still going to visit my mechanic and ask him and I'm still replacing my spark plugs / wires. So now, my light is off!!
