After replacing my intake manifold and carburetor my engine wont start, only sometimes but it would sound ugly and run very roughly at 400 rpm. PLEASE HELP


You have leaks in your gaskets. or vacuum lines removed and not replaced or broken in the operation. trace air leaks with propane torch unlit. where engine speed increases, you have an air or vacuum leak.

It sounds like you need a good tune-up, such as spark plugs and/or wires. They will act up when cold and when warmed by engine temperature will let the engine run smoothly again. And possibly a distributor cap/rotor.

Won't start when engine is cold,


Have someone check your fuel pressure regulator, hard cold start can sometimes be caused by that.

It is likely your timing belt/chain has slipped a notch. Remove timing cover and check valve timing and condition of belt/chain. If you need help, please let us know.

Engine looses power going up hill, no check engine light at this time.


How old is the Catalytic Converter, sometimes they will get clogged up and affect performance.
Good luck
