^Thanks..if disco'ing the cat doesn't fix it, next thing will be to pull the fuel pump and look in the tank.
With all the rain we've had, water in the gas would not surprise me!

You should double-check on a warranty with this car. Do you still have the paperwork from the sale?

Driveability symptoms such as a drop in fuel economy, lack of high speed power, rough idle or stalling are classic symptoms of excessive backpressure due to a plugged converter. Checking exhaust backpressure and/or intake vacuum will tell you if there's a blockage
Pretty sure he got the same warranty as I got with Barney.Quote:

When was the last time you replaced the fuel filter? Had a buddy with a car that had sediment that settled in the fuel filter. Once the car was underway, it would block flow and cause sputters and mis-fires. Took forever to figure it out because the car always started and ran fine initially. After stopping, the sediment would settle again and everything would be fine for the next start.
Fuel filter is < 1 year old. It will run fine, sputter for a bit, and then run fine again. I bench tested the coil pack, but maybe I should do that again.
Maybe its a "Feature" your going to have to learn to love..... ;-)
Cheater motor Karma?
How are the injector o-rings? Did you reuse your 93LE injectors?
I seen him replace them with new fancy flow matched injectors! He did that the same time he replaced the engine. ::Afro::Quote:

New fancy injectors aren't always a good thing. If they were actually worked on there is a chance of infant mortality depending on what was done. Ask me how I know.Quote:

I think the best approach might be to A/B as many components as possible from a similar NA side-by-side. Go grab JJ's car and park it next to yours, then start swapping easy-to-remove components.
^Yep, probably a good plan...all the 1.6's will be at the Pro Solo this coming weekend.
They aren't fancy. Still OEM's that were supposedly rebuilt and flow-matched.Quote:

Looks like the expression JJ makes at a pie shop.

Seriously how many electrical items & sensor could be in that fossil? ;-)
- Coil Pack
- Spark Plugs Wires
- Spark Plugs
- CAS
- Temp Sensors
- 02 Sensor
- Fuel Pump
- Injectors
What else??
wiring connections.
A rebuilt flow matched injector cost me a motor when it got stuck partially open.Quote:

Doubtful but here is an easy way to check if its firing without having to tear the car apart. Keep in mind it may fire but still have an issue.Quote:

If you can't find your injectors, I can scare up a set from one of my 1.6 motors.
^Thanks Mike.
On a lark did you check the accordian hose btw th afm & throttle body for cracks?
That will make a 1.6 run all kinds of terrible. I also have coils, sensors, injectors & ecus in my spares collection if you wnt to borrow.
I also have a known-good accordion elbow. That will definitely give the symptoms described.
^I did replace that accordion piece last year, but didn't check it lately...but I will now. Thanks Steve, I may take you up on your spares for testing.
I had a intake hose crack last month that was only 2 years old. I dont think neff could hit something under the hood but you never know.
Has fuel filter been mentioned? Too lazy to look.
I'm too lazy to answer.Quote:
