the car is a 90 honda accord with a 5speed trans not sure the engine size.
I replaced the
Timing belt
distributor
Plugs
Iac
Radiator
Water pump
fuel filter

and it is idling rough. everytime i give gas it chokes out.
Here is a video of the problem :-) hope that makes things easier.

Here is a video of the problem.

 

Sounds like its sucking air from somewhere. Have you tested for vacuum leaks?

 

Who installed the engine? Was the issues there before the work?

 

I dont know who installed the engine before my friend bought it. Before the distributor and IAC it was doing the same thing but not as extreme.

 

So now we are getting somewhere.

At any point was the car running ok?

Do you have a timing light?

 

There is an important ground on the thermostat housing below the distributor. I would unbolt that, clean the eyelet and bolt with a wire brush or sandpaper, then reattach.

 

The car was running good even after I did the timing belt. about a month after it started doing this. I replaced the Distributer and Iac as he took it to a mechanic and told them that was the problem. after that it was still running bad. so I pulled the Timing cover off and redid the belt and reset the timing twice just to double check. I dont have a timing light. where would you use that on this car? are there timing marks for it?

timing set at
Valves (top pully) was set to the pully where it says up in the up position
with the notches on the side level with the top of the engine
Oil pump lined up with the arrow on the shaft to the arrow on the block.
the cam balancer lined up with the no in the side of it with the line etched
in the block.
the piston lined up with the make on the timing to pointing up at with the mark on the block.

 

I dont remember seeing a ground there but I will look for it. the car ran great after we changed the thermostat. for a couple of weeks.

 

it might have some vacuum leaks it was running without the hose hose (forgot the name of it) that goes to the top of the valve cover. he had that replaced by his friend when he had it looked at, at a shop. it didnt help the problem. but there could very well be some leaks.

 

That hose is just a breather hose it wouldnt make your car idle like that. It wouldnt do anything at all actually. Just keeps pressure from buildiing inside the valve cover.

I would take some sort of brake cleaner or engine cleaner and spray it everywhere there is a seam with a gasket on the engine. Everywhere. Even the spots you dont think have any problems. While the engine is running and you are doing this, if it bogs down or shuts off while you spray a certain seam then there is a vacuum leak in that seem.
