Hey guys,
I have made a few posts but have been told it would be best to make one thread for the various topics as they all pertain to my car and keeps the progress and information in one place!
The car is registered as an 86 but I am pretty sure it is a 87 GT, 5 speed. So far the modifications are as follows:
-BBK shorty headers
-Flow master exhaust with H-pipe
-Pretty sure it has a 1988 T-Bird Turbo Coupe rear end disk to disk
-MSD ignition coil and rotor.
-K&N air filter
-Short throw shifter
Possibly more I have not yet discovered, none of these mods were conveyed to me when I got the car except the headers, love finding goodies on a new ride!
So far I have done the following:
-Cleaned and reset TPS
-Cleaned the EGR valve and replaced gasket
-By-passed neutral safety switch
-Cleaned and applied dielectric grease to the salt and pepper shakers
-Repaired tail pipe holes
-Cleaned IAC valve
As well as a number of electrical things.
Most recent dump resulted in the following codes: 31, 44, 63, 85, 94.
31- After cleaning the valve the idle returned pretty much to normal, but it is now back to surging and the code is still there. I believe it is either the EVR or EGR sensor, when measuring resistance from the sensor to pin on the ECM it was all over the map, does this mean my sensor is shot?
44, 94, 85- I discovered the purge canister solenoid is missing, the vacuum line from the gas tank is still there and goes to the charcoal can but the vacuum line from the can to the solenoid (also missing) and than intake manifold is gone and has been plugged. I purchased some tubing and the solenoid but have now realized I need a harness for the solenoid that I can only find in America and with the conversion I can't bring myself to pay like $60 bucks when I have more pressing matters. Also the vacuum lines below the EGR vacuum solenoid ( there are two solenoids and each have two lines for a total of 4) are not hooked up, one is vented to the atmosphere so I am assuming this is where codes 44, 95, and 85 are from.
63- After cleaning and re-setting the TPS this code disappeared for a couple weeks but has returned along with a surging idle that can sometimes be fixed by turning off the car which is another indicator its the TPS, is it possible I got a couple more weeks out of her from cleaning but now it is fried? Is the resistance test concrete?
Aside from the codes, I am burning through oil. I push blue smoke intermittently, I would say it smokes less often than it does. Usually when I come to a stop and sometimes on acceleration. It drives very strong thou, cylinder balance test is good so I am hopeful it is something other than rings or bad valve seals. Wouldn't the car not drive so optimally if it were one of these two things? Plugs are greyish.
Lastly, I have confirmed today that both headers are leaking where they bolt to the exhaust pipe adding to the already rich smell and making it rough to even drive with the cab wreaking so bad. Shouldn't they just bolt up, is there supposed to be a gasket or anything? I can see a space, if it can't simply be tightened, does that mean the previous owner skipped a little fab work and it simply does not fit?
Big rant but wanted to put all the information in one place for anyone kind enough to help, so far I have got lots done with the help of this site! So to recap, these are the current issues:
1) Surging idle (intermittent, thought I fixed it 3 or 4 times than keeps coming back after a few days of good idling)
2) Smoking blue from the tail pipes
3) Exhaust leak at the headers
Thanks in advance for any help getting this car back running the way she should!
