Car in Sig...

 

Accell Coil.. been on there for months.. no problem

Just put a new set of NGKs (.050, then down to .048)in there, along with some accell 8mm wires.. Starts great, idles fine.. Accelerates fine when cold...

 

Since the wires and plugs, Its been a little gutless in the mid-top end range.. Had to drive 4 hours to Austin today.. Now, after reaching operating temp, when ever the Turbo engages, it bucks and has very limited power.. Passing anyone is an absolute joke and my gas mileage, which has never been great, has gone down he crapper.. under 20 on the highway.

 

I have removed my boost controller.. no change, except the car is even slower now:mad:

 

I will be in Austin all week, probably not driving much.. But also not having much opprotunity to tinker with the car.. then the 4 hour drive north.. am hoping to have a massive flash of insight before then.

Im just starting to get familiar with these cars,but is there a timing advance hose or connector disconnected?

Have you checked for any vacuum leaks?

Speed.. No vaccum advance on 87 and up, so no dice there

 

Cougar. I check to see if I had knocked a vacuum hose loose or anything like that, but couldn't find anything. Don't hear it sucking air anywhere..No change in idle.. acceleration is even ok until boost hits...problem didn't arise until after spark plug and wire change.. intake gakets replaced about 3-4 months ago..

 

The car has always had a tiny bit of surging, but that has been the norm for both of my turbo soobs.. this is just ridiculous though.

 

Thanks guys, keep them ideas coming:D

Were the wires the type that are pre-made, or did you have to make the ends up? I would check all the SP connections, they have a habit of not going on all the way when they are new. Same with the disty cap. Oh, and make sure the cap is ok too.

They were the ones I had to cut myself.. I will check them over.. just realized that I don't know how old the cap is.. I changed the cap 6 months ago, but then switched distributors. different year disty.. different cap style.. and here I have been thinking I have a new cap on there.

Could be simple as a leak in the plenum. Soon as boost comes on, it leaks out. So the car ends up runnning way rich. Check the tightness of the 2 rubber connectors.

 

Maybe you took the plenum off when you did the plugs, and didn't get it seated properly...

did you try putting the old wires back on to see if it went away unless you were having problems with them too

maybe you just need to add a bit of techron to the tank. Sometimes when you do a tune-up, stuff that has been building up for awhile can come loose and slightly clog and injector.

Forgive me if I missed this.

I am prone to try and not overlook the simple fixes.

How old is the fuel filter?

The leak in the air input stsyem (turbo to plenum)

will cause plumes of black (read very rich) smoke out the rear,

have you seen this? If not...

It may be a fuel delivery problem.

As always hope this helps

as you know turbos have a knock sensor and this is exactly the thing that happened to me when mine was going bad and/or poorly connected. Make sure the connector is firmly attached and if it is I would put in a new one. It is a cheap fix.

 

Hope this helps.

My 88 RX started doing that same thing a few days ago. Runs good when cold then slows down after it warms up. I think I have a boost leak. If I ease onto the gas I can hear rushing air before the turbo begins to spool. Im going to work on it tomorrow if I get a break at work. Ill let you know if I find something.
