    Great job Ronnie. This forum is the best for all the wisdom, facts, tricks, and forgotten knowledge that is found nowhere else. I have resisted becoming a Facebook member and as a result I believe I have more spare time.

    Minor issues after engine work

    I agree. When I turn the key on with a pressure gauge installed the pressure jumps up to 45 psi and holds without dropping if the engine is not cranked. If the engine is started it drops to about 36 psi running.

    coil pack/ignition control module

    I believe fixed vs adjustable refers to the Crank Position Sensor being tightened with the mounting clamp and adjustable as opposed to a fixed style which I have not had the fortune to see. The adjustable type needs to be carefully adjusted so that the gapped rings on the back of the harmonic balancer have clearance inside the CPS coils.

    coil pack/ignition control module

    I have replaced a few CPS's without taking off the wheel. It depends on whether or not your harmonic balancer is a tight fit or a slip fit. You should be able to remove it with your hands after the bolt is removed. There is a good trick for loosening the balancer bolt. First remove the vibration dampener and bracket. Put a socket and bar on the balancer bolt and bump the starter. Be sure to unplug the ignition module or the spark plug wires. You may need to put an extension pipe in the socket handle so that it stops against the frame or the floor. Start with the wrench already against the frame or close to it. The engine will turn clockwise which will loosen the bolt.

    MPG woes

    Looks more and more like a stuck or leaky injector. When the ignition is turned off it takes awhile for the pressure in the fuel manifold to bleed down and if an injector is leaking or stuck open a lot of fuel can enter the manifold and give you the symptoms you describe. You might try this: First put a pressure gauge on the fitting that sticks up out of the plastic engine cover. About 45 psi with key on and engine not running. Note that when the key is turned on the fuel pump runs for two seconds and then shuts off if the engine does not start - for safety reasons but the pressure in the manifold should hold. Pressure drops to about 36 psi running. Lacking a pressure gauge that fits the fuel rail you can try this: Run the car and warm it up. Then shut it off and immediately release the pressure in the fuel rail. Take the cap off the fuel pressure fitting and press the center post in the middle of it. CAUTION Wrap a rag around the fitting to catch the fuel. Take the necessary precautions or take it to a shop. After doing this let it sit awhile or over night. Does it start and run better or differently? Is there a Dr. Injector nearby? That might be the next step. Clean and balance the injectors. One troubleshooting tip I forgot to mention is in diagnostics. You have the ability to shut off each injector one at a time and observe the effect on engine idle. Get into diagnostics and with the engine running scroll to the Override section. I believe the keystrokes are explained in the Reatta Quick Reference Guide. This can reveal the problem as well as which injector is suspect. One more thing to check could be the fuel pressure regulator vacuum diaphragm on the fuel rail. Could be leaking internally. Good luck. Let us know what you find.

    Transmission glitch ?

    Yes I believe daily driving does help to keep everything "happy". Probably it is more accurate to say that the driver is much more familiar with the slightest problems as they develop. Easier to troubleshoot if only one thing is wrong and you stay on top of things. I take pride in being able to say EVERYTHING (except the cassette deck) still works after 29 years and 102K miles.

    MPG woes

    I have always used 87 octane with or without ethanol no problem. Exactly what codes are popping up? Are they current or history (or both) ?

    1991 Reatta Stall

    Fuel pump can be checked with a gauge attached to the port that is on the fuel rail. With all other accessories off you should be able to hear the fuel pump come on with the key cycling on for 2 seconds then it stops if the engine is not started. About 45psi with engine off and about 37psi running. With no codes the likely place to start is the ICM or the Crankshaft Position Sensor - CPS. Good idea to change both but change one thing at time. ICM is about $100 CPS is about $35 Both are available from local auto parts but the http://thereattastore.com/ has already researched the most reliable part numbers. Good luck

    Reatta Concept's

    The wheels in the first photo are outstanding. Best non-stock wheels I've seen.

    Possible 1989 Reatta Purchase, "Needs Brakes," Worries

    The on board diagnostics on the touch screen on '88 and '89 models were a marvel that was and still is "over the top". However as already stated there was no programming that could detect bad Ignition Control Module or bad Crankshaft Position Sensor. I carry spares and the tools to change them. Either failure will produce a no start condition.

    Possible 1989 Reatta Purchase, "Needs Brakes," Worries

    That's great advice on the brakes. Plenty of support in this forum. We all love to hear that another Reatta has been brought back to life.

    "Clashing" Sound when Accelerating

    Harmonic balancer? Mine rattles or clatters slightly when accelerating. Does the noise come from the passenger footwell area?

    harmonic balancer

    My '89 is a slip fit and I am glad it is. I have changed plenty of CPS's. Good that they changed to a non-adjustable CPS. Too late for us. I use a couple thicknesses of tape on each side of the slotted ring in order to align the CPS before tightening the clamp. Are there any better ideas?

    Reatta Fuel Injectors are 30 years old-Should they be replaced?

    It is primarily about making all six injectors behave the same. I had mine cleaned and balanced by DR Injector and it now runs VERY smooth. Pricey but a worthwhile investment.

    Is it actually the tranny?

    You may have more than one issue here. That highway mileage is much lower than it should be. I get about 27 highway and about 17-18 in town. I have been having some shifting issues lately and so I changed the transmission shift modulator. Easy to change, under $20 and mine shifts smoother now.
