Im not familiar with the part in question but I take it theres not enough room to get in with a small hacksaw and cut a slot into the head Ive previously been able to get torx heads out by hammering a flat-blade into two opposing notches but this depends on having the exact size of flatblade and it being hard enough. Also if your torx driver is just spinning the head might be too far gone for that.

Sounds like the ecu cables playing up (the covers split somewhere and letting moisture in). WD40 them then seal up with insulation tape
I doubt it is steprer motor problem. On 1.2 engine most common fault is Throttle body position sensor. Fortunately there is no need to change it in most cases. Putting the washer between sensor and engine will probaby solve this problem.
Nothing more to do to it just bolt it on and go. T.
Hi mate i dunno about this one but you can try www.fiatboo.co.uk as its the specific bravoa forum and some very knowledgable members on both here and there. Try the search function first on it though.

if its a 1.6 then it will definately be the idle speed control valve. remove it then clean it using petrol. This usually sorts the problem out. If this fails to work you need to replace the air temp sensor this is to the left of the idle speed control valve (the sensor on the far right of the inlet manifold closest to throttle body). A scrapyard sensor will do dont waste moeny on new parts. You can also try a scrapyard idle speed control valve if cleaning yours does not work.
All conectors is connected but who knows maybe iz something disconnected and I cant see it from above the engine. Today I drive car to service they will change some sensors to find out where is the problem. Yesterday I removed the inllet pipe pipe which connects the air filter and stepper motor. When I was watching the stepper motor flap (butterfly) I noticed that when I want to starts engine the flap

Mainly based on better options being more available. It was known for camshafts being destroyed through oil starvation and not being very fuel efficient since its fuel intection system only used throttle position RPM temperature and Lambda sensors to work out fueling it didnt have MAF or MAP sensors. 1.2s and 1.6 are better engines plus theres lots of parts available both used and new since fiat
Idle control valve or stepper motor. Not sure on that model but Ive never heard of a butterfly position sensor either Oh and you posted in the wrong section
Thanks for the helpfuil advice as I say Karls wife not a normal user Came into the correct forum for my car and as everyone else seems to be posting technical stuf in here I thought that was normal Sarcasm was spot on though thanks As for the stepper motor thats the name of the part according to fiat and Bosch the manufacturer. The butterfly position sensor is the name of the sensor according to fiat

Hi I often put meths as an octane booster the car runs much better these cars like good petrol and the higher the octane the better. This problem sounds fimiliar. What year is the car And do you know what injection system it has This engine had 2 different injection systems (well kind of different) in the bravos the early 1.2 had a cable throttle and the later ones had a fly by wire system. We have
There are some very good advisers on the board and a few of them are in this string...and Im not one of them. But when I got my first bravo 1242 16v CF3 I had problems too. Check your plug colouring to see youre getting a clean bang check the HTs and coil and battery &8211 for a new owner it might be an idea. I found a tear in one HT lead and when I replaced along with nice strong Varta and new plugs

just replaced the stepper motor with a brand new one that fixed it trying to stall on me everytime i stopped but this starting problem has stayed
sounds like it could be the stepper motorincidently you can reset the ECU yourself by disconneting the battery for 20 minites and reconnecting. haynes manual would cover fitting the stepper motor though there never usually a hard fit
Originally Posted by Deckchair5 ...it will probably be your idle valve or stepper motor or idle pot or idle actuator which are all the same thing. On the coops this can be removed and cleaned with WD40. Something to try before thinking of replacing the part. H
Try 3 washers between the stepper motor and the throttle body first. See here

Originally Posted by Wakka What is the function of the three washers I put only two washer for screw but the problem persists... After I put washers I had to reset stepper motor or not Its to distance the tb from the actual motor. In this picture there are 2 moving parts the gear and the disc. You need enough spacers to distance the point on the tb so that it interacts with the disc only not the gear
[quotekickassjay1543118]hey ill let you know im going to get one from the scrap on the weekend it could be the tps thats nakered or its the ECU out of sync with it need a new one anyway broke the clips when i took it apart lol works tho still hope a new tps solves the problem dont like it bodged with [quot hi seen the same problem the new trottle stepper motor needs to be programed to the ecu fiat dealer only
been on a diagnostic but the owner gave up when it did not report a fault which makes me think lambda as they often do not report. I also need to re-assess the noise there is a noticable clunk when letting the clutch up and a lot of chatter in neutral I think the gearbox bearing may be shot feels similar to when my Uno went the same way (input shaft) and I see it seems to be a weakness on the bravo
Right Ive bought a new throttlebody and stepper motor and fitted and tested. It hasnt helped. It still stalls when taking foot off the accelerator. Mickeybravo Not sure Ill have a check for that when I get back. There is a spark plug looking light that is quite sporadic. You know the one that youre supposed to wait to go off before starting the engine well that comes on quite often. What is this cause I read the manual but couldnt see how it related to my situation.

Thanks for the help guys Update THe car has been into a garage and the diagnosis machine reported the following faults Control module diagnosis fiat Motronic MA 1.7.3 Error Memory 463A - Immobilizer Engine Control Unit - Blocked 0203 - Speedreference-mark sensor - no signal FFFF - Control Unit Knock Control Module - Faulty The mechanic told me he managed to clear 2 of the faults and we are left with
myn did that when i first had my bravo its was the stepper motor and had to be plugged in and cost around 90 pund i think.
does the kangarooing happen when you take the foot off the accelerator padal if so than the stepper motor is probably at fault.
I was going to suggest looking at the fuel pump relays but if it does it on gas too... How good is the stepper motor

break anything. There&8217s also some people reporting that a throttle cable that is too tight leads to a high idle and there&8217s mention to a plunge thingy but I&8217ve personally never seen that in my car my fault surely. Answering your questions 1) You can replace the stepper motor independently from the injector unit (not an expensive item) and it is compatible with lots of other cars (fiat

for Karl1990 - and others i have the same 1.4 12v engine mine had a habit of stalling when warm. it turned out to be the stepper motor. It had lost the fine control necessary for idling. I had no money to buy an other one so I improvised on my TB i have a small screw ( small torx ) that pushes on the stepper motor (on the part that moves) what i did was i screwed it in a few turns until the car wouldnt

forgot I have changed the lambda done so much and with a genuine fiat part not a universal jobbie the ECU is an exchange so should not be that air leaks sprayed easy start over the inlet side of things and no increase in engine speed timing is spot on done properly locked the cam etc etc ECU reset done loads thrashing it to clear it. lots of that. seems to be something to do with the stepper motor
