I have three problems with my car engine:
1. oil leakage.
2. missfire for #3 cyl (P0303)
3. manifold differential pressure sensor circuit malfunction (P1400)

I was told to replace: calve cover gasket, upper intake gasket, spark plugs, plug wires. And the total cost is 500$, including labors.

I am wondering if I do some by myself. Are all there problems serious and need to be fixed immediately? What would be the consequece if I delay them.

Thanks.

if you delay them for a couple of weeks to a month ,there should be no problem, if these are actually the problems of your vehicle. you can always replace your own wires, just do them one at a time. mapp sensor should be hard for you to replace, thats another name for the manifold sensor.
