Problems starting..........

[matt_132]

Hi guys

I have a 53 plate 172 cup and I have been having trouble starting from warm. It starts and runs fine but once it warms it develops a very slight missfire. If you turn it off hot and leave it for anymore than 5-10 minutes it struggles to start, turning over freely but takes a while to catch. It has had new coils, leads, plugs and I have cleaned the throttle body out. It also had a new injector on cylinder 3 recently.

Anyone experienced similar????

Oh and when turning ingition to on, the step before starting, there is a high piched noise coming from the throttle body motor thst doesn't stop until the car it started. Is this normal?

Exactly same problem as me even though mines a 1.4 , if i turn the ignition on and off again it seems to help but i have never got to the bottom of it , if you find the problem let me no mate

Will do pal. Anyone have any thoughts? I'm thinking another injector may be at fault. However when the injector on #3 was pissing about it ran like dog shite and threw up engine lights. I suppose one could be on its way out??? I'm perplexed.

Cheers , i think most people would say its a tdc sensor fault as it sounds similar but mine was changed not long back , im now thinking a fuel pressure issue or something like that , does yours feel abit sluggish when this happens ?

No mate runs fine. Goes like stink and runs normal over 1500rpm. Very strange cars!!!
