Throttle problem

Okay. You want to take your reading from manifold vacuum after the carburetor. Can you hook into one of those vacuum lines and resend the video? If that gauge is acting differently then that explains why your guides appear to be okay.

Okay. Yes if RPM is ranging then vacuum will as well. However, I just re-watched that video of the vacuum and that is swinging wildly and the RPM sounds steady.

Can you send me a new video with your timing set around 8 BTDC and at idle and lets see what it is doing?

Basically, things just are not adding up that if you don't have vacuum leaks and the valves are not the issue then we are missing something in the conversion from one engine to another.

Okay. I have to back track a little because I just realized I have been looking up specs for a 1980 2.4L but you said you have a 1985 engine, correct?

So for a 1985 2.4L 144.4 22R-E engine the base timing spec is 5 BTDC and for a 2.4L 22R engine it is 0 BTDC.

Do you know which you have? If not, I would set it at the more advanced number because you said it seemed to run better with more advance.

You always set base timing with the advanced unhooked.

So I attached the chart for timing on the 22R engine which says it should be 0 BTDC at 600 RPM.

For the 22R-E engine it says 5 BTDC at idle and idle spec is 750 RPM.

The next document is the timing advance specs. You should not need to adjust this but you can check your advance is accurate. So set your base timing and then run the engine at 2500 RPM and you should see the timing with the range of the last column.

This also has your distributor number on it which should help identify which engine you have. Clearly it is going to be a 2366cc engine but I don't know which one to tell you to look at so you will need to look for the ID number on the distributor.

This is all to get your timing set properly. Once it is set, send me a video of the vacuum gauge and we can go from there. I hope setting this timing properly will resolve most of this issue but we have to try and "back door" this to figure out which engine you have. Let me know and we can go from there.

Sorry for the confusion.

Sorry for the multiple posts but I just found the actual procedure for a 1985.

Give this a read and let me know what happens.

Oh. Ok. Yes. Vacuum reading with it hooked up. Thanks

Ok. Great job. That makes sense. It was a vacuum/air leak but just not in the area we were looking. I am sure there is something else leaking but as you state, if it is running well then I wouldn't worry about it.

Thanks for the update and using 2carpros.
