No Power

Car has no power. It was bogging down under full throttle. I check the turbo for play, and all seems fine. I replaced my plugs, and the did look to be a little dark. After I replaced them some power came back, but now I can barely get it to go back up my driveway. Please Help.

 

Could be a number of things. Maybe a bad coil pack?

 

any issues with throttle at idle? Rev okay? all hoses connected?

give us more to work with

 

Without giving more information its close to impossible to diagnose what's wrong with ur car. We can sit here and guess at it all day to no avail.

What Mods if any do you have? What was the last mod and when?
How many miles on the car?
When did this start?
When was your last oil change?
How much oil is in the car?
What kinda of gas is in the car?
Have you checked your grounds?

See..we need more info.

 

Idle is real rough. Every thing was good, then this started after I had my oil changed. I only use premium gas, and the grounds look fine. This all started right before c-mas. All I have done to my car is intake and turbo back exhaust.

 

Possibly oil sump tube situation. I have had those same kind of problems and it was my oil sump tube and had to have basically a new engine put in...

 

vacuum leak?

 

Y-Pipe still connected?

 

MAF good?

 

Car has gas?

 

It's tore up.


LOL but seriously. Check the basics. Spark, fuel, compression.

Does it fire up and idle at ease?

 

Damn...I would expect that from a doughboy or something.

 

I totally missed that.


Hmmmm bad coils usually idle ok from the few failed ones I've fixed on others cars. I say huge vac leak. Or even possibly a fuel pressure issue. Change fuel filter lately?

 

On a 2.0L very unlikely.

 

more likely compression/ringlands. do a compression/leakdown test

 

Hey, I have an idea, take it to a mechanic that knows WTF he/she is doing.

 

Yeah....this is a wild goose chase with the info we have.

 

Don't we have a new site sponsor that can take care of this kind of thing?

I would take it over to them(Allpro) and let them take a look at it.

 

Lol. I can't contribute to these threads because I don't know enough to say anything.
So I read and try to learn.

 

but, it's so much fun to keep guessing!

 

What intake?

 

Thanks to everyone! I will be bringing it to a shop.

 

I've narrowed it down to no spark to the cylinder closest to the driver. I replaced the coil pack, but I'm still not getting spark. Plug just keeps getting fouled. It also is the only coil pack I can un-plug with the car running and there is no change in the idle. Any ideas???

 

is the coil pack you replaced it with good? (i usually just rotate them around the cylinders). otherwise, could be a short in the line to the coil pack (rubbing, or melting somewhere?)

 

coil pack replaced is brand new.

 

I had a friend that had a bad ground on a Miata causing miss firing issues, could be something to look into if the coil pack is good.
