>he didn't buy the TRD LZR

>>15821618
her engine is the Mazda 1.8 L FP-DE DOHC I4 with 91 kW (122 hp) if that helps anyone

it's the same as many mazda 323's

>>15821618
Do you even know what wires and plugs he used? Hopefully ngk or denso. You should take it to a different mechanic. One that doesn't just throw parts at it.

>>15821618
It could be a whole number of things. Is there a CEL? When she's "getting up to speed" is it shakes/stuttering or does the car rev really high but doesn't move?

>>15821618
Does she have problems starting it?

>>15821734
nah the revs dont move, they stay low in relation to the accelerator position
>>15821746
it used to have a starting issue, however it's mostly resolved now, but it can take a couple of seconds to turn over most days then some times be pretty much instant (not in relation to temperature)

>>15821776
I'd probably check the fuel delivery system, check the fuel filter, then check the throttle body to see if its full of gunk.

Is this a manual or auto?

This also could be a tranny issue. You said it happens after she comes to a stop while driving. Does it feel like the car is downshifting when she comes to a stop?

>>15821812
it's an Auto, the mechanic cleaned out the full fuel system in the past service

>>15821897
Have you driven the car when it happens?

>>15821919
only once
the accelerator seemed to be completely separate to the revs and it took probably about 20 seconds to start behaving normaly

>>15821950
Would recommend checking the throttle body.
You also could have a vacuum leak.

And ill try and scare you, probably the worst case scenario would be that the ECM is going out, doubtful but possible.

>>15821897
>cleaned out the fuel system
No he didn't.
To "clean out" the fuel system would require removing the tank, pump, injectors etc. He put some shit in the tank that said "fuel cleaner" or some shit. This problem is more than likely a fuel delivery issue. Injectors going bad, rust in tank/lines, clogged filter, pump going bad etc. There are a lot of things it could be. Start going through from easiest/cheapest to hardest/most expensive.

thanks a lot guys, I'll keep a note of both of these

Its electronic
Everyone else can piss off.
Change coil packs is step one.
Its not fuel pressure regulator.
It's not vacuum lines.
It's not the fuel filter.
Its not the transmission.

Could be a ground wire, tps, maf sensor.
Need more symptoms.
Does it "chug"?
Or is it like you step on the gas and it doesn't realize it?

>>15821618
Is this Pasta?

>>15821618
it's the coil shorting to ground, it's a common problem

>>15822468
yeah basically you step on the gas and it doesnt rev as it should

>>15822468
This. Clean the throttle body, check the tps, afm and lastly coil packs. Does it misfire when it won't go?

>>15822750
nah it doesnt misfire, just lags

>>15823617
Tried checking the play in the throttle cable/pedal?

Maybe it's stretched or loosened heaps, hence why the car is slow.

>captcha: 323

>>15823642
nah it's fine, and it's 95% of the time fine, it just suddenly plays up

>>15822057
this is my first guess, especially because its an intermittent problem. is it usually fine when you first start? if so, I'd further guess crapped up tank/ lines/ pick up in tank. change filter cause why the hell not. and also you can then cut up the old one and look for gunk.

>>15822468
this guy is way too cocky and probably wrong and even if right you don't start by changing the coil packs right off. (the ole pay and spray method... good luck with that) That being said, test for spark - 5 - 10 $ tester or free with screwdriver method. I'd rule that out first because its cheap and easy.Then you'll know whether to get into electric or fuel delivery.

wouldn't think tranny either, but low fluid can produce kinda sorta similar symptoms, and its another free check, so check that before getting to the probable issue - fuel delivery
