Brayburks Posted January 5, 2005 Share Posted January 5, 2005 90 legacy2.2 sw. 130k, MT. When the engine is cold, it seems that when accelerating you can't give it too much gas at one time. It seems to jerk and/or miss until you let up on the gas pedal a bit. It works fine if you give it gas slowly. Also, it seems that once the temp guage reaches norm temp it will run much better, but still do it a bit on a load(going up a hill or shifting when rpm's are low. You can't try to take off quickly without it wanting to jerk or surge. If you let up on the gas pedal when it starts to jerk, the jerking goes away. It almost seems like a timing problem to me. Any ideas?? thanks. Quote Link to comment Share on other sites More sharing options...
coloradosubarules Posted January 5, 2005 Share Posted January 5, 2005 Almost sounds to me like a clogged cat. Maybe a bad fuel filter??? Anymore ideas?? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted January 6, 2005 Share Posted January 6, 2005 probably a bad coolant temp sensor. They're pretty cheap. I'd just replace it. Clogged cats typically get worse as the car warms up. Quote Link to comment Share on other sites More sharing options...
Brayburks Posted January 6, 2005 Author Share Posted January 6, 2005 I thought that may be it also. Awhile ago I pulled a code that had to do with the temp sensor. It said it was an irregular signal or something. When I cleared the codes, it never came back. It's funny, when it is extremely cold out and it is first started it runs fine. If it is in the 40's, it surges and hesitates on acceleration. It will clear up for the most part when the engine reaches norm temp, but on a load it will come back. You kind of have to feather the gas to keep it smooth. I'll have to try replacing it, but the nearest subaru shop is like 50 miles away.

cookie Posted January 6, 2005 Share Posted January 6, 2005 and change it yourself. Its a piece of cake unless you are outside at 20 below, and then all bets are off. Quote Link to comment Share on other sites More sharing options...

ezapar Posted January 6, 2005 Share Posted January 6, 2005 Mine have each done that a few times. I say it's clogged injectors from bad gas. I just filled it with Super and added some STP fuel injector cleaner. Like new. Quote Link to comment Share on other sites More sharing options...
Dazed Dreamer Posted January 6, 2005 Share Posted January 6, 2005 flushing the radiator could help just a thought Quote Link to comment Share on other sites More sharing options...
Brayburks Posted January 6, 2005 Author Share Posted January 6, 2005 flushing the radiator could help just a thought Would that help? and how? Something to do with temp sensor? Is that the sensor on the rt bottom of the radiator? Quote Link to comment Share on other sites More sharing options...
cookie Posted January 6, 2005 Share Posted January 6, 2005 sense except that it clears up when warm. I don't think a clogged radiator would do more than help since it would warm up quicker. Quote Link to comment Share on other sites More sharing options...
Brayburks Posted January 6, 2005 Author Share Posted January 6, 2005 at one time I tried to clean the tps(b/c I had read about others cleaning it with good results) but I found that the sensor was held together by rivets. It looked expensive and I didn't want to damage it. I once damaged a $650 air flow meter on my 89 4-runner by poking around somewhere I shouldn't have been. Luckily I found one in a yard for $90. Is there a good/safe way to clean the tps? Quote Link to comment Share on other sites More sharing options...
