Computer code from O'Reileys and AutoZone both read p1239.

The car had been starting slow (4-5 seconds of cranking) for a week or so. This continued until it stalled one day while driving and would not start again. The air filter was recently cleaned.

I took my car to the shop, I was told that my computer needs reprogram by the dealership

It's been setting a long time ! It starts right up but then the reduced power light and check engine light comes on and it doesn't have any power ! Will some one please tell me what to check or replace?

Its a second genaration 3.5 and the check engine light and reduced power light is coming on it runs but no power ! Can some one tell me what to check or replace ?

You can take off drive about 10-20 feet and it turns off and dies was driving fine started about 4-5 says who si metimes it will drive fine

i am having eratic issues every time i drive. loss of power, eratic upshifting, dumping way too much fuel, backfiring, to rear breaks randomly engaging while driving and almost locking. If i clear the check engine light codes, it drives fine for anywhere from10-20 miles, then any of the previous happen again. Codes such as multiple misfires to bank2 fuel rich to abs .. they are never the same.. leads me to think the ecm is base cause.. sending improper signals for these to happen.. getting 126miles a TANK, but the random rear brake lock out of the blue to loss of power as if bogged down, to eratic upshifts are all seperate issues.. it has an electronic throttle body control unit which sticks at times but now i am wondering if the ecm is the cause...
i have an 04.. can you tell me if any other year ecm or perhaps an 04 honda passport ecm would be compatible and/or in fact possible cause?
I am a mechanic by trade, never seen anything quite like these.. snapon codereader explains each thing individually, but nothing tells me other than my gut that its all related to ecm and/or wiring harness..
any thoughts at all are needed asap

tar-like substance leak from the bottom of both the front and back doors on the drivers side of the vehicle.

what would cause a rough idle
what would cause lost oil to the tone of 2 quarts every 4 days


Very cold about year ago car started ended up with fuel in oil. Took to shop drain And new oil added. Now reduced power light comes on occasionally and goes into limping mode. When check engine light on cruise don't work. Is this a high-pressure fuel pump or what else could be the problem I didn't burn the rings out

I ordered belts from multiple auto parts but they keep getting the one with 191 teeth and my old one has 219 teeth what do I do?

Used transmission placed in my old 2004 Rodeo. Looking at a ballpark as to how much I will pay for labor.

Original problem was "Check Engine" light & "Check Trans" light appeared on the dashboard. 4wd was working fine 2 days before it went in for repair. New TCM was installed in 2007 and has worked fine since, so this should not be the problem. What is the process to make the TCM recognize the new transmission? Is there a way/code to reset the TCM?
