Hello I am pretty new at this whole car thing but I recently bought a 1991 Honda Crx Si with a 1.6 DOHC ZC engine in it. The car starts just fine and also idles great, the only problem I have is when I step on the gas. The car wants to almost die and the tachometer goes all wacko like down to 0 and then back up to the regular rpm. The car does it in every single gear even in neutral. I was thinking that it could be the distributor but I am not exactly sure and don't want so spend 200 bucks quite yet. If I could get any input it would be greatly appreciated thanks

Replace the igniter. Here's what it looks like and costs:

Here's how to replace it:

Personally, I would replace the coil and rotor, as well, while you have the distributor open.

Thanks txgreasemonkey, I'm just going to get a whole new (used) distributor for 50 bucks its in great condition, ps thanks for the quick reply! You rock
