Any feedback on these regarding fitment to SC400's? Likely to interfere with the steering shaft, but who knows.

Did you guys check the timing marks?

Well I'd be blaming me in that case, haha. I replaced the belt, tensioner and idler bearing and the car was running perfectly fine before this incident. Car runs great again (aside from an exhaust leak now,) just hoping this isn't something I need to go through again anytime soon...

So... it turns out the timing belt had jumped 4-5 teeth. I had checked the timing marks when I first started looking for the problem and I must've done something wrong because when I checked it the other day, it was way off. After fixing the timing belt and some new plugs, the car runs very...

Are you starting the car? Jumper the terminals and make sure a good half inch of the paperclip or whatever is inserted into the diagnostics plug. Then turn your car to the IGN position but don't crank it over. Should work.

I had done that as preventative maintenence a few month ago, but thanks, any thing is worth looking at for me right now. Along those lines though, did you find the stock fpr to be troublesome?

I was thinking about the gas I found on the plugs before, that it may have been because the coil was screwed and not because the car was running rich like I had originally assumed. I will check the fuel pressure again to see if its within spec. I did a search and learned about the dual speed...

Okay, so I pulled out the coils and inspected them again, one has a crack along the bottom, so I replaced both and cranked the car. It started up stronger, seems less of a misfire but only about 30% better. Still idles crappily with the AFM UNPLUGGED and refuses to smoothly rev up. Still dies...

Hey, did you find a resolution to this?

That was quick, haha. I had tried a spare pair of coils and didn't see a difference so ruled it out. Could it be both the afm and a bad coil? Now that I think back, I didn't unplug the afm with the new coils so I don't know if there was an improvement. Is there a way to test both...

Gentlemen I'm at my wits end here, any help or direction would be extremely appriciated, willing to investigate anything/everything. I purchased a '92 SC400 a few months ago, car looked good, ran okay and was generally clean. First things first, I did a full tuneup...
