LS is being slower than norm?

[mrfuzz]

Hello,


last night and this afternoon, I've noticed my 2000 v8 LS to be running a little slower than norm. Its hard to explain. Not so much hesitant, but pickup is slower.

I honesty think its the gas I got, I have been getting bad gas lately, or atleast I think so. Last fill up was a HESS station, and the normal 93. It feels more like regular 89 octane.

Upon pickup it seems slower, not as peppy.

And lately the car hesitates a little bit from 45 - 60. I changed the fuel filter about 900 miles ago, that cleared it up for awhile. When ever I put STP Fuel cleaner in the tank every once ina great while. The car drives VERY smooth, and full of "pep" also take note, I have 75k Miles on the car.

I checked the engine over for oil leaks near the fuel injectors. And I dont see and splotches. Only today I noticed one small splotch on the passenger
side, at very front, Could of been water though. So I wouldnt automatically assume I need new Coils. but could be possible

Any Idea's upon these matters?

Could be a coil on it's way out.

sounds exactly like my situation. 45-60 was horrible near the end. it started out as something i can deal with with my foot, ease off the throttle a bit and the hesitation goes away.

id make sure it keeps continueing. at the end of mine i was so fed up. i got the 150$ coils on ebay, put em in, all problems went away. i had to replace all 8, it was like each of them was equally starting to :q:q:q:q out, so repalcing just 1 didnt work.

Sounds like what is going on with me.

Its not all the time though, Its intermittent. Goes on for a day or two, or maybe even a few hours and clears up for awhile.

This will be some project eh?

if your mechanically inclined, its not hard at all to change coils. depending on mileage you may as well do some plugs too.

sounds like what i started out with. Be at a red light....a lil blip in the rpms once or twice a month. felt like a miss. Then the 45-60 thing started. always in final gear. then it got more noticeable under WOT. rpms would go in little incriments under WOT. not a steady increase. I did what someone reccomended on here and gave it 20 minutes of pure hell. gas was either 0% or 100%. got a misfire on cyl 2, replaced the coil and nothing changed.

I reccomend not beating the holy blue blazes out of your car to get a code. once it becomes more noticeable just go ahead and replace all 8 coils. your either going to replace 1 every couple months and not have a well running car, or 8 at once and know that they are all brand new. i suggest the later with my experience

Thanks for your input

I'm pretty good on the car, I dont horse around with it TOO much but I do get on it every once in a while. And I have been lately. Typically its pretty quick and I have noticed a difference in the RPM bands per say they dont shoot up as quick.

I believe the gaskets have already been replaced on this car though to be honest. I CAN be mistaken though. I bought it from a sales guy who worked for Linc/ Merc dealer here in FL.

Regardless, I'll keep my eyes on it. Once I get frustrated enough I'll make the purchase of the coils and toss them in.

For now, I need new brakes!

I've been looking on ebay for Coils,


From reading previous posts, I know NOT to buy from global auto correct? Simply because they have the extra flang inside the plug.


I took a stop at PEPboys today, they want $56 PER coil so thats $448 for all 8, Quite steep in my opinion.

Id much rather have Motorcraft coils, over cheap aftermarket. Whats your experiences.

 

[mrfuzz]

Any other opinions would be appreciated.

The ones I bought from Global Auto are working out great so far, they fit my 00 LS V8 perfectly but if you have a newer one or a V6 they may not work.

global-automotive sells the correct coils for all "A" VIN coded Lincoln LS's. no flanges. it was something like world-autoparts that sells the flanged versions. mrfuzz, i have been experiencing the same thing as you for a loooooong time. it started off as the 40-60mph hesitation/jerking especially going up hill, as long as a year ago. i had no idea it had anything to do with the coils, i actually thought the tranny was messed up. then i started getting the engine shakes and sluggish acceleration on a straight away, and i knew it was the coils. i will be buying that $150 coil pack, the $38 VCG's from teamford, and probably a whole new set of spark plugs (around $100) to do the job right and never have to worry about it again - i suggest you do the same!

Steagle,


Thanks! I have similar problems. Awhile ago, the car was misfiring bad. I would step on it, to leave a toll booth, and it would have no power! I put some fuel injector cleaner it, and it went away.

Anyways, When I do the coils, I am also replacing the spark plugs. I'm just going to replace them with what ever plugs are in there. I hope I don't need to change the VCG, Wait and see when I strip the car down.
