Hello everyone this is my first time here hope you can help me out.
Ok my mom owns a 97 lumina I had to do some work to it had a missfire in cylinder 5
checked spark was good checked voltage to injector was good pulled injectors
found 1 3 5 to be heavly clogged with what looked to be coffee grounds replaced all
injectors ran great except one thing its hard to start while cold
if the car is warm run into the store go to start it it will fire right upfrom what im getting from talking to her
she failed emissions O2 sensor was replaced and new cat now shes telling me it smells like the new cat is going bad
im at a loss the engine light isent on I dont think it could be the map sensor maybe crank position??
My thanks in advance,
Dom
