I was watching the boost gauge again today and the autometer was holding steady and the factory gauge was jumping around. My question I guess is the factory gauge run off of the MAP sensor and is this a sign the MAP is going bad. The plugs (CR42TS), cap and rotor (CONRAD RED), were changed 4000...

I was wondering what controls the stock boost gauge. It seems to be jumping around erratically. I have an after market gauge install also and the boost on the after market gauge drops when the factory gauge starts to fluctuate. Is the factory gauge run off the MAP sensor or something else? The...

I replaced them about 2 years/20,000 miles ago and they still do rattle. I was just wondering about all of the oil in the intake manifold. It had to be getting into the cylinders and I think that is waht was causing my detination. Can I put a catch can in line to keep oil from getting to the...

I am in the process of removing and cleaning my upper and lower intake manifolds. When I took them off they were filthy with oil. It looks like it was coming from the pcv inlet into the throttle body. Is this normal or is something wrong? If it is normal how do I change it? I have the pcv's...

plugs and fuel filter 1000 miles ago cap and rotor about 4000 miles (I was going to change soon anyway) Chip

The fuel pressure looks fine when I turn on the key it jumps right up to where it is set. I don't see any black smoke when it starts up. I will check the oil. I have read different things about the fuel pressure dropping. After the car is turned off the fuel pressure will hold for about 10...

is there an easy way to tell if it is the fuel pump or the injectors? I don't want to just start replacing parts if nothing is wrong with them. Chip

That makes sense, I found a small leak between the intercooler and the intake. I have tried resealling the hose by moving the hose clamps around with no luck so far. I guess I need to get a new IC to intake hose. Any ideas? Chip

I made this up real quick. Let me know what you think. Chip

There is a throttle body gasket kit GM #17113115 but I am not sure if this will cure the leak past the tb shaft. Price for the kit off of gmpartsdirect.com is $10.17. I bought a kit for when I pull my upper intake to clean it. I figure I may ass well replace the tb gaskets as well. Kit has 3...

My ty has been hard to start in the morning. It seems to be related to fuel pressure. As i turn up the fuel pressure the truck becomes harder to start in the morning. The fuel pressure will drop off after the truck is turned off for about 20 minutes. Is this normal or is it possible that the...

I was wondering how I check to see if my AFPR(Kenny Bell) is working properly? I checked the fuel pressure with a calabrated guage. I saw 62 pounds of fuel at 15 psi of boost when the base was set at 50psi. :( I know that I should have seen 65. I replaced the fuel filter about 1000 miles ago...

I did throw away the pulsor. I have no vacuum leaks in the lines comming off the manifold and going to the afpr and the map. I don't know about the rest. I need to check/replace the others. I do get more fuel pressure then 65psi when the boost spikes form being lean. I have seen as much as 70...

Checked fuel pressure with another guage. Getting the same reading on both guages. When I changed the fuel pressure to 54 from 52 I still get 65 at 16 pounds of boost. I have a walbro 255 high output fuel pump and the fuel filter was changed about 500 miles ago. When I installed the fuel...

I checked the vacuum lines from the manifold to the afpr and the map sensor and found a leak at the fitting for the afpr. I fixed that and still the same 3-4 psi of fuel missing. I still have the origenal vacuum lines everywhere else. A friend of mine has a high dollar fuel pressure guage...
