Last summer my truck started missing a little and I could mainly feel it cruising down the hwy. I opened the hood one night and spayed a little mist of water on the ignition system. Found that my coil was arching a little. Well I bought a coil and finally installed it this last weekend. When...
That's the thing it's not throwing any codes. It has developed an intermitent miss. I've replaced, plugs, wires, cap, rotor and intake manifold gasket, and fuel filter. I haven't check my fuel pressure yet so that's next.
I'm thinking I may have the same issue. I recently had my intake manifold gasket replaced and about a month after I got the truck back it started stubling (intermitent miss) like the OP. My question is when the shop replaced my intake manifold gasket did the spider injectors have to be...
Well I was wrong I apparently put Bosch platinum spark plugs in the last summer. I usually keep the old ones and the ones before these were champions. Anyway last night I used a water mister bottle to spray down my ignition system from the spark plug to the distributor to the coil. I have...
I've done a lot of research on this forum and many guys are having the same issue and what I have found is it's the AC-Delco spark plugs. Everyone is moving to either Autolite or NGK. I have the AC-Delco in mine and I'm pulling them and I wish I had my receipt from O'reilly for these. By the...
Ok, I went to O'reilly and had them pull a new coil from the shelf and I had my ohm meter with me and it read the same as my coil. Next I used their fuel pump tester to test my fuel pressure. Pressure came in at 63 psi. Anyone else have any ideas?
Sorry it took so long to get back on this but my son has been driving it. But I drove it to work and the whinning is very pronounced from 65 to 75 and then suddenly is less pronounced above 75. I don't know if it hits a different "octave" at that speed but it is much quieter over 75. Also it...
OK the coil test again showed 0.4 ohms and the manual said it should be 0.1. Per manual it says it's bad. Odd. I couldn't find a procedure for checking the ignition control module. Any ideas on that? And I'll have to purchase a fuel pressure tester to check that.
You suggested coil. Is there anyway a coil can send to much or not enough juice to a spark plug?
Reason why I say that is the Chilton manual gave me 3 test procedures with an ohms meter. It passed 2 of the 3 tests. The manual said if it was not 0.1 ohm on one of the tests then it needs...
