i have a toyota corolla 1.6 gti ae92 g reg 89 and its losing power through gears at higher revs. before it would do 130+ mph

and now it struggles to do over 110 mph. what could be wrong. ive been told it could be exhaust but ive had it checked but they said it was ok and a mate of mine had same problem and his exhaust was ok but when he took it off it was all clogged up and his cars ok now. can ne 1 help

could be fuel filter but had you changed any thing else before it started

since i've had my head gasket changed mine has a "kick" at about 4-5000 revs.

i know thats not a lot of help but i mentioned it due to the high revs part

i had a flat Battery but didnt change it for a while and every morning i had to jump start it and then i ran out of fuel and i mite have sucked up dirt

[Sandman]

spark,timing,cap & rotor(if applicable),fuel filter,dirty fuel injectors, bad fuel pump,dirty air filter,bad catalytic converter,bad o2 sensor(s), loss of compression, valves not seating properly, bad valve springs, low tire pressure,bad wheel alignment, bad fuel pressure regulator.

All possible contributors of loss of power.

clutch maybe ?

the guy that said his Rolla kicked at 4,000 thats quite normal its where you hit the power band (max torque/bhp) i've manged to drop my hit down to 3500 giving much more useable power :) :) :)

also you may want to take off your throttle body and clean it out, this will allow proper fuelling and air mixture which helps immensly.

as yours is the tvis engine check that the system is working correctly i have known these to fail an you only run on 4 inlets instead of 8
