I hope some one can help!
99 Impeza wagon love the awd in winters in Minnesota but runs bad at this time.
problem
Bogs down when giving gas on low end.
Took battery cable off reset ECM and will run great for about 25 to 50 miles then runs bad again.
changed plugs, wires, fuel filter, air filter even looked at trainy did flush and filter STILL same issue.
Even boggs down when leaving from a stop and will run fine when it hits about 3500 RPM.

 

Also forgot to tell you ther is no engine code that comes up.

 

Clean your maf or mao sensor?

 

sorry for lack of knowledge, I know maf, but what is a mao?

 

By the way thanks I'll swing by and get cleaner on way home from work, give it a try and reply back on how it worked

He meant map sensor. Probably typing on an iphone

 

Thanks again got to getting back to watching bad guys. I'll clean both items tomorrow after my wild ones get to school.
