Loss in low-end power - Toyota Nation Forum : Toyota Car and Truck Forums

Recently I have noticed a loss in my low-end power, but it kicks back at around 3000 - 3500 RPM. My car is an 87 with a stock 3SFE. I have tried fuel injector cleaner and oil treatments. Any ideas about what's going on with my car would be helpful. Thanks

Most Toyota cars reach their peak HP at 3000-3,500 rpms. I had the same engine in a 87 Celica. My low end rpms weren't bad, but they were not good ither....mabey a tune up?

i have a blown avalon and i have notice a great decrease in my low end power until about 2500rpm, and its killing me off the line! im getting smoked by every POS out there. I am trying to figure out whats wrong, I checked vacuum hoses, but didnt see anything there, could it be a faulty fuel pump or dirty filter?? I have no idea, any suggestions ?? or has anybody experienced this before? thanks

Just had a tune-up and replaced my leaky fuel pressure regulator, could that be it? The fuel filter was replaced about 1500 mi ago.

Did fixing ur leaky fuel pressure regulator correct your problem?? because maybe it is something with my fuel system?
