I have a 1990 Civic Hatchback SI that has a stock engine with about 230k. I just did the clutch, tie-rods, and had an alignment done to factory specs. At 20% or less throttle, it drives fine, but more throttle than that, especially with any aggression (high rpm's, lots of throttle) and the car pulls to the right hard. If I let off the gas and cost or go light throttle, we drive straight again.

I'm running out of options to check. I've confirmed the motor/trans mounts are good as well. Any ideas?

The car has been auto-crossed and is well prepared for STS, but this all seems to have happened just recently. Thanks folks!

 

Check stabilizer link brackets and sway bars for binding or signs of breakage. Check the bushing may be gone and thus leading to uneven stabilization in front as high revving. If that is not the case, one last check would be the double wishbone front trailing arms and control arms issue. Do you drive auto or stick m3 and much you bought it??

 

I'll be sure to recheck those things, thanks. I paid 16k, and it's a manual. I was in the market for another "family" car and the wife just said to get four doors and four seats. I'm the only one I know autocrossing with two car seats in back! Thanks again, I'll post what the solution is if I ever track it down.
