I’ve done lots of work on the car and haven’t written about it at all.
Last weekend we started it up and ran it around the block. The idle was surging and at wide open throttle it was bucking sputtering. I got online and found a way to deal with the idle. I adjusted the fast idle valve. Thanks EricTheCarGuy. I ordered a new cap, rotor, and plugs.
We also discovered a bit of a leak in the exhaust. The exhaust had actually broken just behind the cat. On Wednesday I towed it to a local muffler guy who also races in Lemons. He’s on the EASY team. I asked him to cut out the cat and patch it up with whatever scrap he had around. We also had him reinforce the lower front frame bit that has out tow bar bolted into it.
Mitch, the muffler guy, did not do what we asked. He did the reinforcement just like we asked. But with the exhuast, he cut out the cat and gave us new 2″ pipe all the way back to the muffler (which is a glasspack). He remounted the muffler straighter and moved it inboard a bit to minimize damage if we get rear-ended. I’m not a believer in bigger exhuast = better. I know that if you go, too big the exhaust can cool and slow down and flow worse. But after the fact I looked it up and found that 2″ is not out of range for this motor.
It does sound good.
So my new cap, rotor, and plugs arrived Thursday night. I put them all in and that seems to have been the source of the WOT issues. The contacts in the cap did not look good at all. The plugs were old. I used the oem nkg copper plugs. They are cheap, I’m just going to check them after two races then pick a reasonable replacement schedule based on my observations then.
Took it for a spin around the block and it runs fine again. BUT the battery light was still on. I noticed that earlier when the idle was acting up. It definitely wasn’t on at our last race. So I got out the multi-meter. Voltage on the battery was 12.45. That’s a bit low. Running, voltage was still 12.45 at the battery and comming out of the alternator. I put the leads on the battery and let it run for 15 minutes or so. Voltage dropped to 12.38. Revving it up did not cause the voltage to go up. A new alternator is not in my budget, and it has to get fixed now. Race is Saturday. The alternator guys in Berkeley are closed on the weekend, so NAPA auto in San Rafael, here I come. Gotta get this installed today and then pack up the gear for next weekend. Lots to do still.
