No power, rough idle
98 SL1, 165,000km
I have rough idle down around 500-750RPM (it usually idles just over 1000RPM). Very little power. When I floor it in neutral the RPM gauge goes to 4200 and pulses. Looking under the hood at lunch time and the PCV hose was cracked/split and flattened. I replaced the hose but that seemed to make it worse. I remember talk on here of cleaning the PCV vavle but the Haynes manual I have only says what it does, no mention of cleaning. My question is, what should I clean it with? compressed air, gasoline, methyl hydrate...? Or should I just get a new one? Does this sound like a dirty or defective PCV valve or should I continue to look for other causes? Any advice or suggestion will be greatly appreciated. Roy |

Check the plugs; I'll bet they're not all firing. And *that* could be due to a bad plug, a bad plug wire, or a failed electronic ignition module. Another thing to check: make sure the exhaust system isn't plugged.

No power, rough idle
Thanks, after doing a little more searching I found there wasn't anybody
suggesting cleaning although here in Canada it's more like $15 for the part (still very affordable). If that doesn't do it I guess it's time to start pulling wires and plugs. I really hope it isn't the cat, it was replaced 3 years ago and I really don't want to buy a new one yet.

That's kinda high. You buying that at the Saturn dealer? The going price at auto parts stores around here (Indianapolis) is about US$3.50-4.00, which is still under CDN$5.

No power, rough idle
I was going by prices from web sites and forums, it was actually $5.94 plus
tax from the dealer. That was cheaper than the other parts stores which were around $7-8 but none of them had one in stock, not sure why they bother to give you a price if they don't have one. As for free testing, we don't have Autozone here (I keep seeing people refer to them for free testing) and it is very hard to get anybody to do anything to a car for less than $40 (even to check codes). After I try the new plug wires I may see if the Saturn dealer will test it for me after I've spent $100+ on parts there. I replaced the PCV valve and hose. I put in new spark plugs (figured they were due anyway and inexpensive). The plugs helped a little by getting rid of the rough idle but it still has the miss and a little hesitation when I give it some gas. I guess next is plug wires ($70, I priced them while I was at the dealer). Not sure what to do if the new wires don't do it but I guess I'll keep following the ignition system unless somebody has a better idea.

I realize that's Canadian dollars, not US, but your dollar is a lot stronger against ours now than it was just a few years ago. Right now, CDN$70 is about US$62 -- and that's a *hell* of a high price for spark plug wires. Especially for a 4-cylinder engine. For comparison, I just bought a set for my Suburban at a local auto parts store last weekend -- and that's a V-8 engine, twice as many wires -- for US$25 (= CDN$28 and change). -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

The cat failure is a symptom of a greater problem. Was the problem ever corrected? Failure to keep the car tuned up is one way of taking out a cat. It could of also been an "Upsale". |

Not sure why it failed but the dealer didn't seem too concerned and I'm sure they were looking as only the emission system was still under warranty. |

Got the miss fixed. It was the ignition coil. Found what was probably the
cause of the failure or at least contributed to it. Somebody worked on it before I bought it and snapped off the bottom bolt on the passenger side. IT is in there fairly tight using just the upper bolt but does anybody know of an easy way to get the broken bolt out so I can get a new bolt in to secure it properly.
