running funny

At about 1800 to 1900 rpm the car begins to shake. This happens in everygear at the same rpm during both accel and decel. I noticed this after I changed out a faulty 02 sensor. However, I guess the rough spot could have always been there since I tried putting the old 02 back in and it did not fix it. The car doesnt seem down on power but this can't be good. Any ideas?

Car is a 98 with headers, bosh 13111 02s and ttp tune.

thanks

Thanks! You're a little far for me to just drop by, but I will probably take you up on the phone call if I can't diagnose the problem myself tomorrow.

Well I just cleaned the maf and tb, and checked all the plugs and plug wires... None of those were causing the issue. I'm waiting for Matt to call me back, hopefully he will have some good insight.

keep us posted as I chased this problem until I've given up after I noticed 2 other fellow ls1's doing the same thing. It got expensive chasing it, I started small and did just about everything. I did new fuel filter, clean maf, clean tb, new plugs, new wires, injector cleaner, seam foamed, checked for loose exhaust, new o2's, scanned, and probably a few other things. New Trans Mount and then I gave up. PLEASE keep us posted if you find an answer. I have an 01 Trans Am M6, 60k, been chasing since 30K.
