1999 GMC Jimmy bogs out when driving

I have been battling with my Jimmy for about 2 years now. We have had the transmission checked, replaced the fuel pump, fuel filters, checked the hoses. I've had it in the shop 3-4 times - no one can figure out what's wrong with it. Any ideas on what could be wrong? It is very frustrating making car payments on a vehicle that won't run.

Have the mass air unit cleaned by someone who knows how, very cheap an if no codes are stored this could be it ,3 very tiny wires in mass air monitor the amount of air flowing into engine, if they get insulated with dirt they give false signal to computer which governs amount of fuel more air more fuel less air less fuel thus a bog results

What would case my 99 gmc jimmy to bog down and run rough when giving it gas


If you have replaced the fuel filter this year, the next thing to check is fuel pressure with a gauge. GM vortec engines require 60psi or more to run.
If the check engine light is on you should also have the computer scanned for trouble codes.

96 Jimmy bogs down when I accelerate hard


Sounds like the fuel filter is getting clogged. It will flow enough fuel for normal driving, but can't supply fuel for full throttle acceleration, causing the engine to bog down. Replacing the fuel filter with a new one should fix the problem.

MAF Sensor and 02 Sensor


Replace the fuel pump with another one.
This is a common issue.
Don't use an "aftermarket" pump; buy one from Chevy.
I just had this exact same issue in my shop. The truck would run for a bit, and then just stop. I had the truck towed in, and the fuel pressure was good. Drove it for a while, with the gauge hooked up and taped to the windshield, I could see the fuel pressure start to drop off. I told the owner that she needed a new fuel pump.
The owner told me that the pump was 2 months old. I went ahead and changed it anyway. A new fuel pump cured the problem.

Testing the MAF and the O2s is not going to tell you anything. A failure, an open or a short would set the check engine light.
Please feel free to get back to me if you desire any further input. Thanks for choosing FixYa for assistance.
