Answers :

BARO: Barometric--MAP--Manifold\015\012 Absolute--and EBP--Exhaust Back Pressures: All three should indicate \015\012atmospheric pressure (14.7psi at sea level) and read within 0.5 psi of \015\012each other, Key On Engine Off.

Good luck and take care.

Do rate this solution.
The exhast should always flow freely
\015\012If a back pressure is your trucks symptom it is more than likely caused by a bad MAP sensor, o2 sensor or a plugged catalytic converter

I need to find the wiring that goes to the oil pressure sensor on a 1993 Chevrolet Silverado diesel pickup that has been converted to gas. Where do I find a schematic of this? When the pickup was converted to gas someone clipped a lot of wires in the engine compartment. Now we are attempting to put it back together as a gas. We have traced all the wires except the oil sensor. Thanks.


Take all remaining wires and "flash" them to a good ground with the ignition on. when you find the one that makes the oil pressure gauge move, that's your wire. Do not make a solid connection when doing this or you can damage systems served by the "w ... 1991 Chevrolet Silverado 2500

2000 toyota sr5 v6, 3400 four cam 24 engine. I was comming back from a short trip, when my truck bucked, then the trucks power would come and go, and it lost alot of power. I was able to drive it back ( about 60 mi ) but it had limited power. Also I have had a check engine light on ( I had replaced my catalitic converter after it had been stolen 6 mo ago ) but the truck was running fine. After I got back I checked to see if something had blocked the air intake or the exhaust, both ok. I disconne


Best guess is its a fuel delivery issue. I would check the fuel pressure to make sure it is within the range it is suppose to be. It could also be on the return side. A bad fuel pressure regulator could cause the system to have low fuel pressure. Bef ... 2000 Toyota Tacoma PreRunner

If the pipe got cherry red while trying to start, it was because of unburnt fuel entering the catalytic converter, most likely. Check for signs of plug fouling and injectors hanging open. You're likely flooding your engine due to dirt accumulation in ... 2000 Nissan Xterra

2002 F150 Temp reads hot and loss of power. The truck is not running hot when temp gauge reads hot and when I shut off truck and restart the gauge goes to normal for about a mile then back to hot. It losses alot of power when this happens and the oil pressure light also comes on. I have checked the coil, catalitic converter, fuel filter, fuel pump, spark plugs and spark plug wires. Please help


You could try another oil pressure sensor or test the oil pressure with a gauge at the sensor port. If you think about it, the truck goes into a failsafe mode when there is a problem. You could go into failsafe with high temperatures too. The water ... 2002 Ford F150 Regular Cab

My 1999 GMC Jimmy is encountering problems... It will drive out just fine for 5 minutes or so, but then it starts losing power, almost like something is creating way too much back pressure, but I'm not convinced that it's the Catalytic Converter. Any thoughts as to what else it could be?


Do you have a check engine light on? if so my next question is after losing power does it ever seem to pick up again while running? if the answer to these questions is yes then you may just have an o2 sensor goin bad or something of the sort. if that ... 1999 GMC Jimmy

86 nissan hardbody extracab z24i tbi 2wd pickup engine accelerates normally up to approx. 2800 rpm then acts as if hitting a rev limiter, problem just started with no previous symptoms upon starting out.

Fuel pressure is normal, no misfiring, no glowing converter etc. Please anyone seen this b4? I also cleaned the maf sensor and checked for intake air restrictions.

Could be a plug cat but you fuel pressure is low for this vehicle, it should be 55-62 psi, I would check the fuel filter on the frame and see if it is pluged, this can also take out the fuel pump, make sure the pump is not growling it should sound sm ... 2000 Chevrolet Silverado

Hi, I have a Eagle Talon TSI AWD 1990 175000km bought new. the motor runs flooded & the turbo is always on but sometimes it falls back to running normal, like new, the gas pump pressure was checked, the exaust was disconnected to check if the catalitic converter was plugged, the gas filter, most of the sensors, the coil & wires were replaced, air filter too & the filter unit was checked and is ok.

The check tire pressure light has been coming on erroneously Almost since day one on our 2001 Toyota Sienna CE .Now the check engine light has come on and we were told by a local Toyota dealership that all three cat-converters must be replaced and there is a chance the computer would have to be replaced. They said if the veheicle had 80,000mi.or less the computer would have been replaced at no charge.Naturally,ours has 126,000mi. Replacing cat-converters seems unlikely to me.We always use unlead

It's an automatic transmission (4 gears) and there is an overdrive button on the end of the gear shifter. I've had the vehicle for several years and the way it's always worked is that in order to shift to fourth gear you have to press on the overdrive button and then immediately release the button back to off, then the vehicle would shift into fourth.

2003 jeep grand cherokee 6cyl. Oil pressure drops as engine warms up.replaced sending unit, same. Checked with mechanic's pressure gauge and found out gauge on cluster is correct. Pressure drops below 5 when the engine is warm.Removed oil pan and found pickup screen was clogged by sludge.Replaced oil pump and screen, cleaned oil pan. Now pressure stays at 10 psi at idle when warm. However, it can not create pressure after start up, light stays on until you rev engine up and bring pressure close


The reason it differs from cold to hot is because your oil is thicker when cold, as the engine heats the oil thins a bit causing the drop. Good news is, you do not need but about 7psi at idle to keep the engine properly oiled. (to bring oil to the t ... 2002 Jeep Liberty
