1.4 Hesitation.

[CraigW]

Ive searched but cant really find anything for my problem.

Since Friday my car has developed a hesitation. Used it on Friday and it was fine, left it overnight, got in on Saturday at roughly 5pm and it was there.

The best way to describe it is when Im picking up speed it gets to a certain point then hesitates for say 5mph then is ok. Then if you change up a gear it does the same thing. But when the car got warm it was alright.

Ive checked all the vacuum hoses and they are alright, the throttle body is clean as I did that when I changed my airfilter. No water mixing with the oil or anything. Sprayed the usual places with wd40 incase water was affecting it. So I have narrowed it down to a few things.

Spark plugs/leads on way out.
Temp sensor of some sort.

Im thinking it could be a temperature sensor as it did it this morning on the way to work until the car had warmed up properly. But when I came out of work it never did it once as the air/ambient temperature was high.

Hope someone can help or suggest some other things to suggest checking.

Cheers,

Craig.

Mate my old mk2 had the same sort of symptoms, i tried everything and it tuned out to be the coolent temp sensor, get it changed not expensive iirc,

The sparkplugs would most likely give you a flat spot.

I thought it was maybe some sort of temperature sensor because by this afternoon when I left work it was really warm and there was no hesitation. Thats what got me thinking a sensor of some sort.
