matched inlets.. Help :)

[henryp]

Hi all, Just fitted my matched inlets. got a bit of a problem. my car now misfires.. if i put my foot down, it just misfires till about 3k then it runs alrite.. if i rev it up when not moving/not in gear it sounds fine..

anyone help?

Plugged all the leads in the right order?

Something must be loose mate or broke when you refitted it, coilpack/leads all ok? One wasnt loose and you moving it tipped it over the edge?

 

[henryp]

yup. everythings all plugged in and okay..

 

[Greeny.]

Thats a lie, its not okay at all

 

[henryp]

haha well, yea. but the plugs/leads/connections seem okay.. i've triple checked.

I'd put my money on a vacuum hose, either not fitted correctly ( if at all ) or damaged in the process.

 

[Andyman]

Plugs on all the injectors correctly ?

Plugged all the leads in the right order?

What difference do that make?

 

[Russ_16v]

the cylinders fire at seperate times, so the spark is put in at seperate times, so if the plug leads are on wrong, then the spark will be put in at the wrong time and the car will run badly

 

[mx1_champ]

if it was the plugs in the wrong order it would be missfiring and spluttering all the way through the rev range . a good way to check is to get some wd40 and spray that around the inlet when its running ( not into air filter/ throttlebody) if there is a vac leak somewere the car will bog out or die . then locate leak and sort the problem .

 

[jack_davey]

yeah blatantly a vacuum leak...

 

[henryp]

I've had enough for tonight, took everything off, checked everything. put it all back together and it's still doing it. I'll carry on tomorrow. with the wd40 (ty mx1_champ). the only thing i did noticed is that when i put the upper inlet on, the bit with renault sport on it. it doesnt feel like its sitting down properly, i can rock it slightly. must be a problem there with the vacuum leak as said. my back f**king kills me from leaning over so much...

Thanks for the help guys.
i'll let you know how i get on tomorrow after work!

 

[henryp]

Still no luck.
It's definitely missing on no.2 cylinder.

im thinking HT leads / Coilpack..

anyone know rough prices for these?

 

[sideways danny]

sounds like you need to take the upper inlet off and see what's stopping it sitting down. Could be pinching a lead

 

[henryp]

I've already sorted that out, was just some s**t built up.. its now sitting flush and level when i put the upper inlet on..

Sorry to jump on the thread but what does matching the inlets actually do!?
Roughly how much does it cost?

 

[franx]

many of the OEM inlets are badly cast , not good for flow. The little edges are machined away "matching" them to the rest of the ports , in short.

What effect does this have on the car?!

Is it expensive? Seems very popular.

All depends how bad your original ones are, you might be putting £200 down the drain but on the other hand it might give you another 2-3bhp.

Jamsport do it for £138, i'm currently diy-ing a spare set, so if they make no difference all i loose is a bit of time.

back on topic ; problems solved !?

 

[henryp]

not yet.. trying new coilpack / leads tonight!

 

[henryp]

faulty leads.

i shall order some tomorrow, as i was only trying off a friends car, trial and error.

thanks for the advice dudes.

 

[Chrisjk]
