Gas Hog(3MPG)

Yay! The first time I've driven my car in 11 months!!! I had a lil over 1/4 tank in it. I started to slowely drive it around the parking lot in circles keeping the revs below 4 and the boost below atmosphere. I have a few issues, and I'm sure they're all associated with it being brand new and needing to be broken in but, I need some assurance.

1. The car likes to stumble while accelerating. I'm just thinking that I keep getting in that zone of not hittng the gas hard enough to keep the revs up because I don't want it to boost. It does this terribly when shifting to second. @ 2500 in 2nd I feel like I'm riding a bull.

2. It sucked soo much gas. I drove 10.2 miles and used 1/4 tank, whoa, what's up. The course of this driving was very light throttle below 4k, plz tell me it's a break-in thing.

3. My headunit, clock, and domelights do not work. They worked fine with the old motor, all fuses are fine, could my harness be fried?

Thanks i advance, mods are in the sig.

That gasoline was probably not in the best condition having been sitting for 11 months or more. You might have fouled your plugs out also from the bad gas. Just a thought.

Well the gas is new, the old gas was only about a gallon and has been "idled" out, this was the first time I drove it, but it has been started and ran a few times.

Some of it is the weak engine (will increase with time/mileage), some of it may be timing. Check your timing, if it is a tooth off it will drive like **** but stil run.

They usually get bad mileage the first few hundred...

adjusting the tps will help with the bucking, may not solve it completely tho.

All I need it reasurrance, I'll check the timing and adjust the TPS when it's broken in a little better. Thanks guys, I feel better now, how about that wiring?

there is no reason not to adjust the tps now. having it set properly will help you better asses the progress of break-in. all you need is a multimeter, screwdriver, and 10 mins.....

Maybe your fuel level sender or guage are out of whack. 3MPG is seriously bad for just driving around in circles.

Whatever the problem is....

You got owned! Hardcore!

Wow...and to think that I was bitching about 12MPG. Good luck and that's definitely not normal, not a normal break-in mileage(it's pretty shitty, but not 3MPG), and your 3rd problem is MOST LIKEY your fuse. I had the same problem before. Also make sure to check with one of those fuse checkers, my fuse looked fine, but it was blown.

We checked his TPS and his timing tonight.

We couldnt find any good instructions for the TPS, so I just kind of winged it. I looked at the lower plunger, and we ohmed it down to 1, using the two wires I thought would have worked the best with my S4 knowledge, the green and the black one. Didnt seem to make too much of a difference.

Also, awhile back we restabbed the CAS when installing the motor. Well, I checked it tonight with a timing light, and the first mark was about 70 degrees advanced.

We put it back as much as possible, but its still a good 20-30 degrees off. Also, I thought there was some plug that needed to be jumped to do the timing. There wasnt one specified in the haynes manual, and the internet access where the car was wasnt cooperating with us so we couldnt find out for sure.

Anyone know the jumper? Did we ohm off the right two wires for the TPS?

O.K. man, start the car up & let it warm up till it idles down...get some alligator clips for the meter leads, and a piece of fairly stiff wiring (paper clip, maybe)...ground the black lead to the stud sticking out of the throttle body (or any good ground, really) via the alligator clip...stick the stiff wire in the green/ red stripe wire terminal on the TPS connector (on a '88, anyway), make sure it's in there good for a good electrical connection, and attach the red (pos) meter lead to it, via another alligator clip (the clips are just so you can free your hands- make life easier)...with the engine idling, you should be getting 1 volt DC, plus/ minus .1 volt or so. turn the screw on the throttle linkage (might have a plastic "cap" on it) above the TPS area to adjust the output voltage while you're looking at the meter. This is a rough adjustment, but it'll get you in the ballpark...I've found more accuracy using the "test light" setup (with a couple of meters instead of the lights), but the voltage test will at least show you how far off you are to begin with. Good luck...
