car seems to pause

[mikes-fat-arsed-estate]

The latest addition (the cabby) 1.8 zetec seems to pull nicely from low down as soon as it hits 3k it seems to just pause for a few seconds almost like it doesn't want to be pushed any further obviously it will if i keep going but sluggishly , my 1.8 tdi pulls better is this just a case of me expecting more from the car or is there possibly a sensor gone bad?

so far I've tested the maf ( car stalls if unplugged)

Cleaned the throttle body , now going to reset the ecu & test later tonight so see if any improvements

I've just give the car a service oil - filter , fuel filter , full tank of shell v power ect

 

the ones I've watched on YouTube seem to pull nice & consitant through out the rev range

unplug your lambda (the plugs above the radiator under the cross-member/slam panel).

 

if the pause vanishes then you need a new lambda/o2 sensor.

 

the car will run fine with it unplugged for the short term though the ecu will over-fuel the engine and itll run rich till a new sensor is in (iirc)

sounds like a maf or lambda as shaw said. my si used to do this all the time. the clip for the maf sensor was broke and kept coming unplugged

Nice one cheers fella`s i will give it a go tonight

[scottybo]

did u change the plugs? maybe one of them is on its way out

[mikes-fat-arsed-estate]

yes i changed the plugs forgot to mention them , ill take it for a run tonight if its still doing it, if so i will unplug the lamba to see if theres any change & report back

My 1.8 si did that I gave the air filter and lambda a clean works fine now.

We've moved this topic into the correct section.

cheers peewee

 

took the car out tonight it seemed to be a little better then normal unpluging the lamba sensor didnt make a difference how ever im starting to consider it may be just me expecting to much from it. but doesnt have alot of over taking power.

 

is this normal >?

 

if so mines no where near that haha

Cat blocked or collapsed, if not the O2 sensor, it need a new cat.

 

 

I've got a 3 door 1.8 Si and a 5 door GTI, both standard engines and there's more than enough overtaking power, certainly not sluggish.

 

I've also got a 96 Escort Rs2000 with performance cams and superchip, performance of which can not be compared to that of the 1.8.

 

I say the YouTube footage is of modded Escort, either Rs2000 or a 2L Zetec.

my other daily ride which is now being stored in a friends warehouse is a mapped vw passat tdi currently running 180bhp maybe im just feeling the lack of 80 horses haha & all that low end torque the diesel delivers ,

thanks for your opinion on the youtube video that would explain it.

I've never driven a Passset TDI, especially one that has been chipped, so can't compare but I certainly wouldn't describe 1.8 Zetec Escort as sluggish, both mine pull great and are on par with vast majority of newer cars.

 

If one fiited, I believe the Cat is blocked or collapsed.

 

I had similar a few years ago, Escort would run and drive perfectly around town but lacked oomph.

 

On motorway would cruise all day at 60 & 70mp but couldn't get above that.

 

Once cat temporarily removed, oomph returned and motorway driving back to normal.

good excuse for a decat by the sounds of it lol
