So I fixed the Cat converter and now the car has no Power. It runs fine, but up hill it doesn't have that same power it use to have? I did rebuild the engine, but I haven't re adjusted the valves. Do I have to do a valve adjustment with a torque wrench?

Also, I have a 500 watt amp hooked up, and ever since that, when I put my signal light on, it dims out and all my dash lights flash with it. Could this be my Alternator?

 

Have you checked your engine timing; camshaft/crankshaft and distributor timing? If timing belt were installed incorrectly or ignition timing off badly, it would cause loss of power.

Unless you have a fuel cell generator in the trunk, your Accord will not support a 500A amplifier. The 500A is probably not continuous, but certainly exceeds ability of your vehicle w/ any engine/accessory load. Alternator is only good for perhaps 100A, if you have the high output alternator.

good luck

 

500 watts is like 35 amps (using 14v). Still big, but not impossible.

 

Well, after 8k miles, it started lagging one day. I do Daily Drive the car 90 miles home and back.

So are u guys saying that a 500 Watt amp is way too much?

 

So is the power 500 watts or peak current 500 amps? I suspect that 500 watts is correct.

If 500 watts, then load may be acceptable if other loads are minimized. I think you might have problems, but I've never operated one of these large amps.

good luck

 

So I checked my timing, my valve clearance and everything checked out... I am running a "gutted" cat. Do you guys think that the o2 sensor is messing with the ecu and causing it to have the lag?

 

Have you checked compressions? Low compression would reduce power available.

good luck

 

if you have your 500amp hooked up to woofers your putting a hard load on your alternator and it will eventually fail. you need to put at least a 2 farad capacitor in... this will stop your lights dimming when the bass hits and keep your alternator from strain.
