Puma 1.7 Rebuild Mk II

Post by raggamuffin » Tue Apr 30, 2019 1:29 pm

2 week lead time in the clutch. 3 sensors and other bits to be fitted this week.

Clutch will have to wait until beginning of July when bodywork gets done

J said he's checked over the TPS already. Checked the readings/parameters of the sensor and ensured they were within the manufacturer spec. So it's all working well.

He does have another throttle body he's going to try to see if this will solve the judder issue. As it's only occuring when the accelerator pedal is slightly pushed, he thinks the throttle body might be letting in too much air.

He also said that it'd be best to prioritise the manifold, cat next. The bearing rattle isn't an urgent fix, and he said the current mods are probably only half as effective without the manifold/cat.

So, as it stands - 3 more sensors, door cards, strut braces, new coolant header tank to be fitted this week. He also said he'll clean up the headlight plastics.

July - fix bodywork and alloy wheels.

Aug - fit 4-2-1 manifold and sports cat (connected to original exhaust system).

I decided to speak with the eBay seller about end term bhp goals with the Puma and they recommended a Stage 2 clutch.

So I've sent the £41 extra via PayPal. This Stage 2 clutch requires 500 miles bedding in. Which is good in all honesty, as I need to save more on fuel. Then again, this won't be fitted until Jul/Aug.

If you decide to replace the throttle body, you will have to reset the adaptive values again, i.e. reset the PCM and again let it to relearn the idling values...

Would it not learn them without the reset? J seemed to think it would.

With time yes. But until it does you would have erratic idle again. Since you are unsure what the problem really is, I would take all the knowns out of the equation if I could. And idling etc you can. You are putting on another throttle body which is not new, so it has some leakage around butterfly. That is not a problem if PCM measures it and takes into account when activating IAV. If not, you will be again at erratic idling as the PCM would try to compensate for the values that are not the same as the ones stored in the memory.

Nothing new to report. Awaiting J to work on it this weekend due to delays recently.

Stage 2 clutch should arrive soon too.
