My 1994 toyota camry 4 cylinder has poor engine idle, unstable rpm driving 30 miles or more, every complete stop I make it and after trying to accelerate it dies however no hard start, poor acceleration after a 50+ miles drive. So inother words alot of problem on road trips but it does really find in city. Ive changes spark plugs, gas filter, trans oil, engine oil, alternator, starter, TPS Sensor, distributor and rotor. Was thinking maybe fuel pump?
