69-90

Hi I'm posting this for my brother cause he is computer illiterate, im normally on honda-tech but anyways he was driving fast on the freeway for about 10 minutes and was running fine and parked the car and came back in 10-15 minutes and got back on freeway and car seemed to of lost power and was running bad and idle was really bad. got back and looked under car and cat was glowing red hot. so far we have dropped cat and cat was fine not warped or clogged was able to see through cat, changed spark plug wires spark plugs two coils ,changed CAS crank angle sensor and lined everything up like it says in the manual and adjusted timing with gun. the car idles steady now but still has no power, the plugs on left side of motor top and bottom are dry and right side are wet. car will rev up and backfire seems to be only running on two plugs car runs rich anyways any help or suggestions would be appreciated thanks.

Have you check motor compression?

69-90

no not yet ill check it out though, if the compression was bad wouldent it be smoking alot?

The cat may be burning excess fuel. I'd def. check compression, but I'd also pull sparkplugs, attach ign. wires, ground them, and check for spark to be sure it isn't an ignition problem. How is it idling - on one rotor? See if you can think of any more detail to add.

i would try taking the leading pug wires, the ones on bottom, and switch them on the plugs only, leav the wire atached to the coil loacated in the front of the left fender. the leading pugs fire as one as it is. so if it is a spark problem with one of the leading coils this will let you know.

fireing order.

trailing plugs = t0 - 0t - t0 - 0t - t0 - 0t (top plugs)
leading plugs = LL- LL - LL - LL - LL - LL (bottom plugs)

key
t = spark ( for the top plug only)

L = spark (for the bottom plug only)

0 = no spark (all plugs)

reboot

hey kyle, check compression and make sure you've got all the firing order right.
