SC400, 95, 125K--Driving home and at a stop light I noticed a change in engine dynamics. Engine developed a muffeled sound and as best I could describe it –almost like it was the potato in the tail pipe. Now, when I took off from the light, I had little power. Also as I increased the power while in 1st the tach “bounced around” and dropped to zero but the car keep plodding along (thus it didn’t reflect the decrease in RPMs), shifted into second tach came back to est RPM, then dropped again to zero as I asked for more power (very slowly at that) and shifted again but remained at the designed RPMs. Funny smell from exhaust, no check engine light, Xmission fluid is normal flavor. Sometimes I have been concerned about the Xmission as it makes a “whinning” noise when it first starts out but then clears up and no slippage. No real visible signs under car or engine comparment.
Now before I throw up my hands and take it to the shop—what are some quick checks???
Thanks to the forum and the tech info on timing belts, window regulators, and front end bushings as I am getting ready to do the timing belt/pump (maybe).
