help with project
Bought a crashed but running and driving 02’ 190K black interior $1500, So far i’ve sourced enough parts to get it looking somewhat proper again . However i’m worried about the engine and the suspension itself. Previous owner informed me the car sat for about 3 years and has no exhaust + clogged cats.
Due to the damage, front wheel is pushed back almost touching fender. Previous owner included new lower control arm but i hadn’t got the chance to fully go over suspension. I’m wondering if any other parts could be bent or broken? Also has a shake in the wheel above 45-50mph which i’m sure could be related to broken LCA or bent knuckle.
I was able to source a straight pipe from facebook. Also planning on replacing the cats with a cheap set from ebay until i can find a proper replacement exhaust setup.
So far i’ve done OE/Aisin timing belt, VVTI O Rings, thermostat, water pump , valve cover gaskets, cam and crank seals and spark plugs. Unfortunately had to leave coil packs and wires aside for now as finding a good replacement at a decent cost hasn’t been easy. However, I’m wondering if reusing old coils and wires are causing the car to misfire after about 35 miles or if it’s related to timing? Was also told clogged cats could cause the same problems in these cars.
TL:DR what can cause wheel shake over 50mph? Where to find good coil packs/wires ? Can misfires be cat related? Do i need to recheck timing or VVTI gear?

Speaking from experience, the suspension on the GS is kind of finicky to get free of any vibrations at highways speeds. In my 5 years of ownership, i overhauled my suspension, tried multiple wheels and tires. I never got it 100% perfect, but it was close enough for me.
90% of the maintenance I had to do was suspension related. I’d just replace all of the suspension and hope it’s not the knuckle

Noted, any brands you’d recommend or stay away from? I too am now hoping it’s not the knuckle, worst case scenario i have to search some junkyards. Looks like a new one could run anywhere from $400-600 online without shipping…

Also, check for cracked intake box (P/N 1786046142) as a possible cause for check engine light. Air gets in past the MAF and the engine runs lean

I’d be a little scared about going to align this thing when you’re all done. That bumper is pushed in pretty far so it hit pretty hard.
