Why are these cars never easily fixed?!

[b16hbg]

Hi guys, as you can probably tell, I'm getting fed up with this heap of sh*t. Replaced plugs, misfire still present, replaced cap and arm, misfire still present, replaced ht leads, misfire better but still present! Am I really looking at replacing the whole ignition system just to fix a stupid little high boost misfire!??

[daz364]

where is the miss fire ? low revs high revs ?

[b16hbg]

Starts at 4k ish! On full acceleration. I'm gonna have to replace the coil I think

I could´nt fix my high boost missfire problem. So I went MSD.
Still works perfect passed 600hp

I've gone through the same thing.

Fitting a late igniter from a Lexus and a new coil in the morning, will let you know how it goes. Nothing else left to replace

[b16hbg]

I don't think it's an ecu fault, I just think the ignition system on these are xxxx!

[N9THX]

Well i've replaced:

HT Leads
Dizzy Cap
Plugs
Rotor Arm

Same probs, missfire at high rpm and idle or when damp/wet weather.

Coil pack was split, sealed with silicone, same probs.
Igniter is corroded so ordered a very clean later Lexus version.

Along with fitting the coil and igniter, I'm fitting a CT20b turbo in the morning.

Hopefully by dinner I'll have a smoke free smooth running turbo


........................but then again

[b16hbg]

New turbo??! Why? I'm certain mine has gotta be sorted by a coil. Is the igniter the same as an amplifier?

[N9THX]

Fitting a turbo because at the minute it has a CT26 fitted which has just started smoking and it's a good time to fit the correct CT20b

These are the ignition components I'm fitting, both above each other under the fuse box in the engine bay.



About £60 for the coil and igniter.

Where from dude? I've found a coil for 45 quid.

[nickg07]

i had misfire only in extreme rain conditions. replaced loads but replacing the coil pack fixed it i think.

[daz364]

I had the same thing all but a month ago and it was the ignitor they crack and break down underload you can get them from camskill.

Found it finally! Got a tracking line on the coil on the inside where the ht lead connects, left it soaking in oil for the night, order a new on as well from camskill, probably!
