I have a 94 Toyoda corolla that started to sputter a few months ago. It usually only does it when I'm driving over 60mph. I replaced the fuel filter and have checked the wires, they seem fine. I wondering if it could be the EGR valve but can't locate it.
Any sugestions or help would be appreciated.
If wires are original - I'd replace them right off. Add a bottle of Techron Fuel Injection cleaner and clean the throttle body. Air filter new? How are vacuum hoses? Plugs --- replace with NGK or ND never any other brands.
Thanks Wolfgang. I'll try your sugestions.
