I think it's time to buy my Bentley Manual.. been meaning to since I got my car.. but have been cheaping out by using the Haynes manual... (good for the basics.. lots of pictures for braindead's like me.)

thanks for the info contra... my car's been feeling very sluggish lately... very slow to rev up and feels like it's being pulled behind. Now part of it is ... well.. both my rear brakes recently siezed up.. (pretty sure it's the handbrake which siezed up).. but it's not fully locked on... not enough to justify the hesitation I feel. Just cleaned my intake. Idles okay and everything.. just doesn't want to move. Any ideas?

there are a number of things that I know of on our cars that will cause hesitation, I've been meaning to do a write up on all of them some day when I have more time.
One thing I can't stress more though is that everyone's car will feel a little sluggish in the summer time because of the heat and humidity. If the car runs great at night, (and it'll feel different like night and day, honestly), then it's probably just the ambient temperature causing the hesitation/sluggishness.

Now now, don't laugh and shrug what I just said off because even this very summer I racked my brain for hours under the hood looking for an air leak etc which didn't exist and all it happened to be was the summer heat that day making my car feel slower


p.s. if your parking brake is seized, I would suspect the car to want to pull or rock to one side when you first accellerate, no? I've never experienced this, but I would suspect that's what would happen as there's been a few times I've tried to drive away with the parking brake still engaged (oops!)

hey...

yeah I notice the car runs much better when I start her up in the middle of the night opposed to afternoon. But the performance goes down because like an idiot I swapped my stock airbox for a aftermarket ram-style intake which does an efficient job of sucking in hot engine air... especially with the 75watt bulb from the angel eyes right beneath it.

But that aside... the car still feels much more sluggish lately.. I mean, more than normal. The parking brakes are not fully siezed.. just partially. So the car does not pull to either side.. if you jack up the car you can still turn the wheels with one hand... but as soon as you stop turning, the wheels don't continue to spin. Something I will definately have to look into..

any other ideas on my sluggish car?.. I mean the performance feels like it was cut by a good 40% or so from a couple months ago. No such thing as quick accelerating anymore... usually I could drop to 3rd and floor it and the car would take off with a little wheel spin... now?.. I might as well drop it into 5th and floor it.

Where can I get some new ignition coils aside from the dealer and how much do they go for?
How much are they at the dealer?

"steps acceleration" also means i have bad coils?
when acclerating it feels like its changing gears within the same one...as if it has holes all over the place, a non linear thing...

(mine is a m42 engine)

Justin.. I completely rebuilt my M42 and it's still very slugish in humid weather, but not when it rains for some reason. I've never checked my coils but i've done everything else. you may want to replace your catalitic.. that's a major performance killer if it's burnt up or clogged. As far as power loss, unless you have a hesitation or other ignition problems it's most likely a bad fuel/air mixture (do you have a chip)? first do an oil change, replace the plugs, clean your air filter and buy a heat sheld for it.

I would check for bad wheel bearings, calipers and e-brake. go for a back road drive and stay off the brakes as much as possible, pull over and see if any of the wheels at the hub are abnormally hot, you should be able to hold your hand on the wheel and it should be the temp. of a warm breast.

What did you test??? because the M20 engine only has one ignition coil. the newer bmw's have 4 or 6 coil packs

Yup!
But think of it this way, they'll last you at least 10 years afterwards. So 6x $120 = $720 / 10 years = $72 a year to enjoy a problem free ignition system

Coil packs on most cars cost around the $70 to $100 mark anyway, it's just our luck that our cars have multiple coil packs


BTW, and I think I mentioned this in another thread, but if you find your coil packs are reading a 0.9 to 1.0 you might be able to get some more power to the plugs by tightening the gap by 0.005 to 0.030 instead of the stock gap which is 0.035. I did this on my car and noticed a very noticable improvement in the response time of my ignition. Instead of a little pause before firing, they almost fire right away when i tap the gas pedal.
Oh yeah, I also suggest everyone use stock champion copper plugs. Forget about all that other rubbish, the stock plugs run best in our cars hands down. My engine management system agrees with that statement as well when I look at the graphs it spits out. As well many books I've read swear by stock plugs so I'll never go back to platinum or iridium ever again.

Hmm... can someone explain exactly what the ignition coils do? I just read that a rough idle on 92 engines is likely shoddy ignition coils.
