Hello! Your symptoms tell me that you likely have a catalytic converter issue. When the converter becomes clogged, you will experience a significant loss of power and torque. This is often, but not always; accompanied by the smell of rotten eggs, another tell-tale sign of a converter issue.

I hope this helps, and thanks for using FixYa!

1992 gmc suburban has no power and bogs in cold weather


You need to perform an OBDII diagnostic test and look at the stored faults. Sounds like a temp sensor or Mass Airflow Sensor. Also dirty air filter needs to be changed every 40,000 miles. be sure to delete stored faults and recheck OBDII periodically for new faults.

Suburban stalls after iddling for about 10to15minutes,then takes a long while before it starts and be able to drive,sometimes it will start but when I press the gas it bogs down.so I have to let it sit for...


Check engine coolant sensor. If it has a problem, it sends a message to the computer that your engine is actually cold and sends more fuel to the engine causing it to run rough or die. After cooling down it will start and run until it warms up then does the same thing again. Just a thought but could be the problem. You have changed your fuel filter correct? And have you checked your fuel pressure?

I have a 1992 suburban 350 motor. truck had no power and bogged down when gas pedal applied. i changed the filter and now it wont start by itself. i spray starter fluid and it runs fine for 1/2 hour then...


first thing i would do i would check fuel pressure if you have good fuel pressure then the next thing i would unbolt the exhaust from the exhaust manafold and then try to start engine if the engine starts up and runs fine then you have clogged up exhaust converters

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
