turbosubi

Hey guys, I dropped by Hopkin's and had Brian go on a test drive with me. He tightened the throttle cable, but I was able to still replicate the Problem for him. The stumbling only happens between 3700 and 4000 rpm's, very noticeable when cold under load, less so when warm. I actually had to shift into 1st gear at about 25 mph when warm, bring rpm's to 3800 under full accelleration, then when I back off the throttle, it starts to stumble. He surmises a bad TPS or the sensor located between the air filter housing, and the intake ( black plastic piece with a rectangle connector on the side). He thinks he might be able to get both used from a friend of his. After reading all the threads about this problem from other people, no one has brought these topics up. I guess I'll have to wait and see if either of these solve the problem. P.S. I added Baccaruda and Monstaru to my buddy list on this site, since you two are local boys. Hope that's okay.

Thanks, you guys. I'll try out your suggestions tomorrow. Thanks to all who replied, your knowledge is appriciated!

Please see new thread on "Stumbling" I just started. This is becomming a nightmare for me. My mech is a 30 year veteran of Subaru's, but I'm losing faith....

I'll get down to it. 87 ea82t 61,000 miles Engine cold, stumble in mid-pedal range Warm engine, no stumble unless you get on it, between 3800 and 4000 range it starts to cut-out unless you back off the throttle. recently replaced: cap rotor wires plugs fuel filter. see thread "fuel filter replacement/Update Distributor" for history of this problem. mech replaced distributor, ran fine for 3 days, now back to square 1. Cannot afford these repairs, student on a tight budget. Please, Please, Please help, if you can. Thanks Guys!

Thanks, you guys but-I'm OLD. I like automatics. I miss the performance of the 5-speed, coupled with the Turbo, and thought maybe the 4-speed might make up for it.

I read in someone's thread that in 1987 Subaru introduced the electronic 4 speed automatic transmission.I have an 87 GL-10 Turbowagon. Is it an easy swap-out with the 3-speed auto? This would take into consideration that I could find one. Since we've raised the speed limit from 55 to 70+, the engine runs in a higher RPM range than I would like. I'd like to have my soob for 300,000+ miles, like I did with my 88 turbo wagon, but it was a 5-speed (which I miss alot). Any advice out there?

Thanks, I sent them an Email with the particulars, we'll see what they say. Thanks again for the lead.

edrach, I'd have taken you up on your offer in a heartbeat, if I had known that the distributor was the problem beforehand. My mech found a used one, and with installation it came to a hair shy of $200 with labor. Live and Learn. I am interested in the "rebuilder" of Turbo-distributors, located you said, out of Portland, Ore. I think I should probably have my old one rebuilt, since I don't know the history of this used one.

Hi-Read my thread about what I just went through with this same sort of problem with my 87 turbowagon. It's under fuel filter replacement by Turbosubi. It was not a bit fun, and I had to have it towed, for it stopped running altogether. I wish a much easier solution for you

Thanks for the reply. I started at the Subaru Dealership for OEM parts,cap-rotor-wires-plugs, only to be told that they would have to order them:-\ So I went to Napa and got the parts. My mechanic used the new cap I purchased with the swapped distributor, and it hasn't stumbled or bucked since I picked it up yesterday. I try and always use OEM parts, but what a pain in the rump roast waiting for simple ignition parts from the dealer. What other choice do I have here? The used distributor seems to have fixed the problem, so far......but should I hang on to the original distributor? can it be rebuilt with new electronics (keep in mind this is the TURBO distributor)? Subaru Dealer says no......

Picked-up Soob today, they had to replace the whole distributor. They found a used one, but I question, at only 60,000 miles why did it fail? We called the Subaru dealer here in Spokane, only to be told Subaru doesn't make a rebuild kit or optical electronic replacement part for the distributor, only a $600.00 replacement one, since this was a TURBO distributor. I still have the original one that failed, can it be rebuilt? Thanks Pro's, I value your expertise in this area.

Update: I went today and purged the fuel line of any air. It started right up, and ran well until it warmed up. I drove it about one mile, then it started sputtering again, along with the CEL turning on and off while it was sputtering. I managed to limp it back to Hopkin's Automotive, and we'll have to see what they find out. I don't have a clue......

Thanks Shawn for reply. I don't know the history of this car, but I owned a 88 turbowagon for 297,630 miles before trading in for a jeep. I won't even GO to the headaches I had with the Jeep...But anyway, I noticed a bit of stalling when it was cold Friday, So I decided it being 17 years old, to do a complete tune-up before winter. When I replaced the oil-drum sized filter, i lost alot of gas in the process. I surmise since it is a pressure system, the fuel comming into the new filter is pushing air into the fuel rails as it tries to refill the empty new filter.? After it died, the cel would flash on and off, along with a bunch of relays whirrling and clicking in the engine compartment (engine not running) sometimes it would run for 2 seconds, others it wouldn't start at all. Fuel filter is installed correctly, and no pinched lines. It ran fine before I did this???? Very frustrating.

Hi fellow Subi's:) I have an 1987 GL-10 Turbowagon with 61,000 original miles. I just finished a tune-up, and replaced the fuel filter. It ran well for 4 blocks, then died. I checked spark, all good. I didn't bleed fuel system, do i need to? any help would be appriciated. Thanks
